How is it any better or worse than any other form of prejudice? Don't take the high road here, everyone has their cultural taboos. I didn't say anything about this part of this thread, because I know that I have my own.
I suspect the only thing you'll be seeing from me is "WOAH! That's taboo" or just being a little jumpy.
However, as long it is an voluntary act, I can't do anything about it.
Now, I may not be the world's most consistent ethical actor...so I expect others to keep me in line when I got out of hand.
Yesterday, somebody resort to personal attacks. Discipline is on the menu.
