A former Jehovah's Witness has spoken out about the religious organisation's extreme practices in a series of shocking YouTube videos.

Damo Hyland, 20, from Perth, WA, was born in to a family of Jehovah's Witnesses.

He claims he spent much of his childhood being indoctrinated, brainwashed and subjected to emotional manipulation.

Mr Hyland told Daily Mail Australia he was forced to clean places of worship and take part in door-to-door preaching known as 'witnessing'.

He added that he was regularly bullied at school because he was different.

Mr Hyland said he had a particular problem with the 'fear conditioning'.

'You're taught from a very young age to put Jehovah first, and anyone who isn't a Jehovah's Witness is potentially dangerous,' he said in a video posted to his YouTube channel.

'(Non-Jehovah's Witnesses) are made out to be criminals and bad people, and if you associate with them in anyway, it could get you killed.

'I couldn't bring my ''worldly'' school friends over because Jehovah wouldn't like it.

'I couldn't celebrate birthdays, Halloween, Easter... and it meant you were labelled as that kid (at school) who goes knocking on everyone's door on a Saturday morning.

'And I was taught to really hate Christmas.

'I remember going to the shopping centre and Santa was there. He came up to me with his crew and they said 'do you want a picture with Santa?'

'And Mum basically just looked at me I knew exactly what to say: No. I'm a Jehovah's Witness, and Jehovah doesn't like Christmas.

'That is what I said to Santa. Still to this day that makes me feel sick.'

Mr Hyland said that when he entertained the idea of leaving the religious group, he was accused of not loving his grandmother.

'I was very close with my granny,' he said. 'But I was told I mustn't have loved her, or I wouldn't leave the Witnesses. By saying I wanted to leave, I was saying I didn't want to ever see her again.'

But Mr Hyland said the worst part was that no one was allowed to question their situation.

'If you didn't want to clean the toilets at Kingdom Hall until 11pm, you were told "Jehovah wouldn't like that".

'If you didn't want to spend your Saturday 'witnessing' and knocking on peoples doors, you were told 'Jehovah wouldn't like that'.

'And if you didn't want to go to all the meetings, you were told 'Jehovah wouldn't like that'.

'I couldn't play footy because games were on Saturdays and I had to witness on Saturdays, so playing footy wouldn't be putting Jehovah first, and would make Jehovah sad.

'I wasn't allowed to sing the national anthem at school. I had to stand on stage in front of the school and the Australian national anthem would come on, and I had to stand there with my mouth shut and not sing it.'

Mr Hyland left the organisation with his father when he was 14 years old, after his parents separated.

'When I left, my eyes were opened. Everything from people, to the way the world works, working in general, and the internet. Porn Hub. Everything.

'You know that if they could see if like you have they would get out. Because it's just so obvious when you're out that they manipulate and control their people in a very unfair fashion.

But leaving the organisation created its own problems for Mr Hyland who said he was 'shunned' by many of his former friends.

'(If you leave), you're going to lose your family and friends because you've been brought up to not have worldly friends. So when you leave you've got no friends,' he explained.

Despite an unorthodox childhood, Mr Hyland speaks very highly of both his parents, including his mother who is still in the organisation.

'I can tell when they've had a meeting about Armageddon or dealing with loved ones that aren't Jehovah's Witnesses because she just becomes a different person towards me,' he said about his mother.

'She acts differently, she talks differently - she just becomes a different mum... But my parents are very good people and are both good parents, and I feel they're both now comfortable with where they are.'

Jehovah's Witnesses told Daily Mail Australia they respected Mr Hyland's his right to have and express his own opinions, but could not verify his experiences.

'It does not appear that Mr Hyland was ever baptised as one of Jehovah's Witnesses, and we don't know if his parents are Witnesses or just attended meetings,' said a spokesperson.

'There are many misconceptions and controversies concerning religion, and while his comments are based on “personal experiences”, it does not reflect the experience of over 8.5 million baptised Jehovah’s Witnesses in 240 lands worldwide.'
