There is nothing the least bit benign about having utterly no tolerance for views that differ from one's own, Ebbie. Such intolerance leads to such evils as (and I quote directly from your list)...

intolerance (obviously)
bias
discrimination
fanaticism
injustice
partiality
racism
sexism
unfairness
cruelty
abuse
jingoism
hostility
violence
hatred
exaggerated self-righteousness
witchhunts
kangaroo courts
hazings and harassment
insults
bullying
mob rule
lynchings
and authoritarian oppression by those in positions of power

It also leads directly to the suppression of lawful free speech in a society.

If a great many people here who imagine themselves to be good "liberals" (and they're not such good liberals as they think they are) were not showing that just sort of bigotry toward people with any different opinion than their own and thereby attempting to gang up on and SILENCE those people, I would not be posting here at all.

The gay marriage issue is not one that I have much personal interest in...nor do I object to such marriages. I object to gangs of people (whether they are "liberals" or "conservatives") bullying, insulting, and demonizing someone else who's not in their "club".
