Rather than filter it out, respond to it with facts, tolerance and logic. They (racists, the REAL ones) hate that as much as liberals do (but I repeat myself- to-MAY-toe,
By tolerance I mean putting up with things that I don't much like but that don't really harm me or others. Like the fact that 70% (+/-) of black folks are born out of wedlock. I don't use that because it does me or no one but themselves harm. If I say it, it is processed by others as hate speech rather than as a fact. If the queers want to call their unions marriage, let 'em. I don't agree, but it's not a hill to die on. Bad policies, OTOH, affect us all. YMMV.
