Do you think you could gain knowledge without using slurs and ad hominems? The only reason to do that is to provoke and hurt feelings.

Could I or could anybody? Funny you mention ad hominem and targeting the question to me, implying that I use slurs and ad hominems. :)

I seriously don't care if somebody is smart and I have something to learn I will regardless of her style, slurs or whatever. I learned that in primary school where I was exposed to underpaid teachers who hated everybody who was smart. :)
