This isn't about disagreement; it's about creating a hostile environment for women at MIT and continuing to do so for years. I'm not prepared to tolerate things like that.

If we want to talk about disagreement...

He only recently recanted (with quite suspicious timing) his view that pedophilia is fine if the child gives consent. No, I'm not going to tolerate that view. I wouldn't want to work for someone that had that view.

In the email thread under discussion, he wanted to redefine "sexual assault" and "child rape" to something that agrees more with his sense of linguistic purity. No, that's not ok.

At some point, when people keep having disgusting views, and won't change them, you give up on them entirely. It's just not worth the effort anymore.
