@Procrustes,
Sure; have you ever attended a social gathering? What were the topics of discussion?
The internet leaves behind inhibitions and the "rules of engagement" changes, because you're typing on a computer, and not face to face.
Most people's persona changes on the internet. I know I'm more direct, and challenge bull shite when I see it.
I still consider myself a pretty average guy, and get along with most people face to face or on the internet.
I argue with my siblings when we discuss religion or politics; doesn't mean I love them less or don't respect them.
