You do know you can calculate the likelihood of a proposition from inductive evidence.
There has to be some kind of phrasing for that. I put myself in a group, a member of that group does something atrocious I don't agree with, the world at large vilifies the group and I feel defensive because I put myself in that group.

Stand up and say something. The problem isn't that this kid can't tell whether the creeps trying to get at her are from HN or not. The problem is the creeps.
Fight the right battle dude.
