Its inconceivable to most of us how otherwise perfectly sane rational humans can be manipulated into believing the most ridiculous and impalusable things.
Way back when I first heard of the "gender" stuff I came across a seres of videos made by a man "Patrick" who was a desister, and uploaded on You Tube. This would have been around 2014/2015 I guess. He was a multi lingual (he recorded the videos twice in both English & German - neither being his native language), clearly a very intelligent professional well off man.
He spoke movingly in 3 videos in English, about his personal experience of being a gay man who came to believe he was transgender.
What was so shocking to me back then, that really stayed with me a decade later, is doctors and surgeons told him so-called "gender affirming medicine" would actually change his sex - and he believed them!! This intelligent articulate man really believed that these doctors were going to turn him into a woman by giving him cross sex hormones and cutting his genitals off.
He was absolutely brain washed by gender ideology and medical doctors that he was going to change his sex - not his gender but his sex.
He had cross sex hormones, and was about to have irreversible surgery when he "woke up" out of this fog and realised he was a man, would always be a man, etc.
He was absolutely shocked that he had allowed himself to become so vulnerable, so needy, so open to suggestion that he had gone down this route of self harming, and the extent that he had been manipulated and lied to by doctors and medial professionals who should have been helping him, who he trusted to help him.
Gender ideology harms and many vulnerable people are manipulated by it.
The videos didn't stay up on YT for very long - occassionally I search for them in case he uploads them again - I expect he received terrible harrassment for talking about his own experience so openly, or maybe YT deleted them for the thought crime of "transphobia". 10 years ago talking about the gender bollocks publically, online, was expreely difficult and you were likely to be cancelled.
