Considering the fact that he was a sexually abused child at the time, it does seem out of order to harp on about it the way some people do, and to "use him as a weapon".
As I understand it, he raped one person as a sexually abused child. He then raped 3 others years after the abuse had stopped, when he was a teenager - something that he admits that he knew was wrong at the time but did anyway.
I don't think it's wrong to point out that when Myers calls the comment section of one website a haven for rapists because some of the commenters also post on another website which has no connection to rape or rapists, that his comments section is an actual, literal haven for one rapist. It's certainly the height of hypocrisy for the conversation to go:
"This comments section is a haven for rapists"
"What evidence are you basing that on?"
"Some of the people who comment there also comment somewhere else"
"What has that got to do with rapists?"
"...."
"You are aware that the only confirmed rapist commenter in this sphere is a regular commenter on your site and that he gets a lot of support, aren't you?"
"You unfeeling bastard! That's over the line! How dare you mention that a self-confessed rapist is a rapist! How dare you use accusations of rape against someone? How dare you use the presence of a rapist in a comments section as a weapon against the website that hosts the comments section?"
Which is, basically, what's just happened. Are there different circumstances around what's being discussed? Sure. I'm in no way implying that the two are equivalent. But, come on, anybody with half a brain should be able to see that it's a bad idea to accuse someone else of hosting a haven for rapists, when you literally host a haven for a rapist.
