[Again, disapproval of the NAACP and ACLU =/= thinking blacks are "un-American." Save your paranoia and handwringing for someone else.
And, again, I have no idea why the ACLU is even mentioned here.
I mentioned ACLU because the ranking Republican in the Judiciary Comitte called it "un-American" and "Communist-inspired".
As for the other, you seem to be thinking that your opinion is somehow representative of the opinion of the majority of Republicans or Americans. If there wasn't a (big) constituency for that kind of rhetoric, then politicians wouldn't engage in it. Just remember the scorn poured on Dukakis about his ACLU membership.
