The guy was merely corroborating the original post, sharing some of the absurd things he was taught in school, and was downvoted for it. Doesn't seem like a very friendly thing to do to someone who's engaging in the discussion.
Shall we stand by mute while someone is bullied? Either that or be bullied ourselves for speaking up to stop it? If that's it, then I don't like your policies. I re-edit the post to conform to your policies. Then I'll show myself the door, thanks.
