Gay actor John Barrowman is in trouble with the trans community after using the slur ‘tranny’ and then telling those who were offended to ‘lighten up’.

The argument which exploded today first started back in October 2014, when the Scottish-American entertainer posted a video online in which he used the word ‘tranny-tastic’.

It exploded back then, with people writing comment pieces and blogs about how the slur was offensive and as a gay man he should know better not to use it.

He responded in a Q&A video, in which he defended the term, made jokes and called the complainents ‘haters’.

One Twitter user, who found the video, tweeted Barrowman today asking: ‘Do I have to keep you on my list of "Celebs I used to love who disappointed me by being unapologetic asshats?"’

He responded to his 371,000 followers: ‘I think u need to careful, as no one supports the #LGBT community like I do. I think u need to lighten up. JB’

It didn’t go down well with the trans/intersex identifying ex-fan of the Doctor Who star.

‘Just a reminder; if you cherry pick when you will or will not support the trans community, YOU ARE NOT AN ALLY and you need to fuck off,’ she said.

‘After all, it was "just a harmless joke", and I’m "oversensitive" and "need to lighten up" right? It always us silly trannies AMIRITE???

‘Except these "harmless jokes" dehumanize us and contribute to the pervasive attitudes of us being tricks or traps or subhuman freaks.’

Another user agreed: ‘How hard is it to just say "A joke I made hurt members of the Transgender community, and for that I am sorry."’

While another waded in: ‘I’m on your side. Typical cis gay male dialogue. The T-slur is never okay, and as a gay man, he SHOULD know better.’

Barrowman wrote: ‘In general no one knows my struggles or a lot of my history so be careful when u judge and throw daggers. JB’

Finally, the transgender user promised to block Barrowman, and he tweeted: ‘Can all the people ragging and bitching just fuck right off my feed. Please. It’s so dull. JB’
