More hypothetically, can Jean Doe have raped someone and still be involved with social justice movements? Yes they can as long as they take responsibility for what they did, and have done work to make sure they won't do it again.

This... I didn't even know what to do with this. I tried to type up something coherent a half dozen times, and then I just gave it up. No. No, a rapist cannot advocate for victims because a rapist has created a victim. They are part of the problem. And part of their rehabilitation should be coming to realise and accept that they've lost credibility forever in terms of social justice advocacy.

What's more, Kynn certainly wasn't in any hurry to take responsibility for anything. It was Jack who drew attention to the attack, not Kynn herself. She's also posted saying she isn't confessing to anything. So the point, weak as it was to begin with, is moot anyway.

(I'm ignoring the "more hypothetically" past of that statement, because there's no way this is a hypothetical situation.)
