Milo Yiannopoulos lost his $250,000 book deal on Monday in light of his comments that appear to defend pedofiles

Milo Yiannopoulos lost his $250,000 book deal on Monday after video was leaked that showed the alt-right poster boy appearing to defend pedophilia.

Publisher Simon & Schuster said: 'After careful consideration, Simon & Schuster and its Threshold Editions imprint have canceled publication of Dangerous by Milo Yiannopoulos.'

'Dangerous' was set to be published under Threshold Editions, the conservative branch of the publisher according to USA Today.

The book deal received backlash since the announcement in January, with many on social media threatening to boycott the publisher.

Yiannopoulos's lewd comments saying relationships in which 'older men help those young boys to discover who they are' seemed to have pushed the company to back out.

After the announcement, the 33-year-old speaker posted on Facebook: 'They canceled my book.'

And minutes later: 'I've gone through worse. This will not defeat me.'

On Tuesday, the Breitbart Technology Editor is slated to hold a press conference about the comments at 3pm in New York City.

The 'Dangerous' author also published and deleted a 10 minute Facebook video emphasizing he wished he had used the term young men as opposed to young boys during 'The Drunken Peasants' clip.

The video of the comments resurfaced after he was slated to speak at the Conservative Political Action Committee.

Just six days ago, Yiannopoulos wrote on Instagram: 'I asked my publisher, Threshold Editions, for more time to submit the manuscript for DANGEROUS so I could include material about the craziness and rioting at UC Berkeley, UC Davis and UW Seattle.'

Milo Yiannopoulos claimed he was not defending pedophilia when he said some younger boys could benefit by coming involved in a consensual relationship with an older man. He has now been banned from speaking at the Conservative Political Action Committee conference

'Dangerous' was set to be released on March 14 but was pushed back to June 13.

When the book hit number one on Amazon's best sellers last month, Yiannopoulos posted on Instagram: 'I only know how to win.'

Earlier, Yiannopoulos has been uninvited from the the Conservative Political Action Committee conference because of his comments on gay relationships between boys and older men.

The conservative firebrand was told he will not be able to attend the event this weekend by Matt Schlapp, chairman of the American Conservative Union.

He released a statement on Monday saying his invite was 'rescinded' after the 'offensive' video surfaced.

'We realize that Mr Yiannopoulos has responded on Facebook, but it is insufficient, he added.

'It is up to him to answer the tough questions and we urge him to immediately further address these disturbing comments.'

The move comes just hours after Yiannopoulos strongly denied that he was defending pedophilia with his comments.

On Monday, he wrote on Facebook: 'I'm partly to blame. My own experiences as a victim led me to believe I could say anything I wanted to on this subject, no matter how outrageous.

'But I understand that my usual blend of British sarcasm, provocation and gallows humor might have come across as flippancy, a lack of care for other victims or, worse, "advocacy." I deeply regret that. People deal with things from their past in different ways.'

The conservative-leaning Reagan Battalion released footage of the online discussion

Beitbart's Technology Editor was taking part in a debate between several American men, one of whom was wearing a superhero-style mask, when he defended 'coming of age' relationships.

A five-minute edited tape of the discussion was posted online forcing the controversial media star to clarify his comments.

Yiannopoulos was due to address the annual Conservative Political Action Conference in Washington this weekend.

After the footage was released, conservatives called for him to be banned.

During the online discussion, Yiannopoulos said: 'This is a controversial view, I accept. But we get caught up in this whole child abuse thing even to the extent we are policing consensual relationships between consenting adults, such as grad students and professors at universities.

'The whole consent thing is not as black and white as people try and paint it.'

Yiannopoulos agreed that the age of consent was 'roughly' at the right age.

Yiannopoulos wrote a second apology on Facebook on Monday. He said that he was abused as a child and felt he could speak freely on the topic

The controversial columnist is often greeted by protests, such as this one earlier this month in Berkeley, California where he was forced to cancel a planned speech due to the demonstration

He continued: 'There are certainly people who are capable of giving consent at a younger age. I would certainly consider myself to be one of them, people who are sexually active younger.

'I think it particularly happens in the gay world, by the way. In many cases… actually, those relationships… this is one of the reasons I hate the left. This one-size-fits-all policing of culture. This arbitrary and oppressive idea of consent, which totally destroys, you know, the understanding that many of us have, of the complexities, subtleties and complicated nature of many relationships.

‘People are messy and complex, particularly in the homosexual world. Some of those relationships between younger boys and older men, the sort of “coming of age” relationships, the relationships in which those older men help those young boys to discover who they are, and give them security and safety and provide them with love and a reliable rock where they can’t speak to their parents.'

Yiannopoulos said: 'Pedophilia is not a sexual attraction to somebody 13 years old who is sexually mature. Pedophilia is attraction to children who have not reached puberty. Pedophilia is an attraction to people who don’t have functioning sex organs yet, who have not gone through puberty, who are too young to understand about the bodies. That is not what we are talking about.

‘You don’t understand what pedophilia is if you thing I’m defending it, because I’m certainly not.'

Yiannopoulos suggested a relationship between 'younger boys and older men' can be 'hugely positive experiences for the young boys' saving them from possible 'suicide and drugs'

Yiannopouloswrote an 'apology' titled a 'note for idiots' on Sunday. He insisted he does not support pedophilia and mentioned sex criminals he had 'outed' during his career

Yiannopoulos claimed some teenagers could find a relationship with an older man quite beneficial.

He added: 'In the gay world, some of the most enriching and incredibly life-affirming and shaping relationships, very often between younger boys and older men, can be hugely positive experiences for those young boys. They can save those young boys from desolation, suicide and drug addiction, all sorts of things, providing they’re consensual.'

Later, Yiannopoulos wrote on Facebook blaming deceptive editing and his own 'sloppy phrasing' for any indication he supported pedophilia.

He said he spoke of his own relationship when he was 17 with a man who was 29. The age of consent in the UK is 16.

It's unclear who edited the videos.

The video was published by the Reagan Battalion, a blog that describes itself as 'news, information, commentary, from a conservative perspective'.

According to a Facebook post, Yiannopoulos insisted he should have used the term young men as opposed to young boys.

According to a statement on The Daily Caller, Yiannopoulos attempted to defuse the scandal.

He said: 'I do not support pedophilia. Period. It is a vile and disgusting crime, perhaps the very worst. There are selectively edited videos doing the rounds, as part of a co-ordinated effort to discredit me from establishment Republicans, that suggest I am soft on the subject.'

He added: 'I did say that there are relationships between younger men and older men that can help a young gay man escape from a lack of support or understanding at home. That’s perfectly true and every gay man knows it. But I was not talking about anything illegal and I was not referring to pre-pubescent boys.

'I shouldn’t have used the word "boy" when I talked about those relationships between older men and younger gay men.'

Yiannopoulos suggested there may be an ulterior motive in trying to ban him from the event this weekend.

He added: 'This rush to judgment from establishment conservatives who hate Trump as much as they hate me, before I have had any chance to provide context or a response, is one of the big reasons gays vote Democrat.'
