People won't quit bad behaviors. All you can do is call them on it and point it out.And risk being called a racist, or patriot, or christian, or ... american ?
I quit being scared of being called names about 2nd grade. I'm an adult, now. And I've been called pretty much everything in most languages. I was once cursed in Sanskrit (on what passes for paper, I've got it around here somewhere).
It's a very insecure person that worries overmuch about bad press.
Really makes the libs angry when you take away their only leverage. ;)
