Tatchell sadly is never advocating for what he thinks he is advocating for. He is the example of not only repeatedly wanting to be heard framing his abuse as definitely something not positive and not harmful - but also to look for company in advocating in effect for this to be something ok to happen to other nine year old boys. He is unaware that his own lack of appropriate boundaries is a direct result of the harm done to his boundaries as a child.
He is the example of the harm carried by adults who were sexually abused as children. I am very sorry he was not better protected as a child, but he is a sad example of failure, not an example of child safeguarding being unnecessary and something that should be removed. To better convenience the desires and wishes of an adult to use and manipulate a child for their own sexual gratification.
His feeling that as a child he was not particularly harmed by it seems to me in common with the TW view that a lesbian should 'learn to cope' with unwanted, undesired, unsatisfying sex that is nothing more than a duty of their providing their body for the use of a TW. Who will enjoy it, who does want it, and who does not want to be buggered with any reciprocality or responsibility, but sees the other party as a kind of therapist/animated sex toy.
It's a repeating theme. It's a disturbing one. It again lacks any awareness of boundaries or social relationships. It attempts to justify and involve people in wangled consent to being used.
Considering I feel used when someone male comes into a female single sex space where I'm changing, because they want my presence and my state of undress to meet their need to feel affirmed and do not want to have to bother with any reciprocal need meeting or equality of consideration.... where exactly do the lines fall in all this? There is no appropriate justified 'use' of non consenting, unpaid others to provide a wanted service. Society does not delineate into givers and takers. This is not a socially competent view of the world.
