"Yes, of course no one here is a rapist"

That's the controversial claim, all right.

I don't share your intuition, but it wouldn't matter if I did. We LW should be frightened of having intuitions for which we can't, on reflection, give any supporting evidence! And automatically considering your in-group to be of higher virtue or above suspicion is a very well known and widespread human bias. That's why we picked on your claim.
