One thing that has always bugged me - the Civil Rights Movement took place, and we got rid of stupid things like segregation; there seemed to be hope for "diversity" in its real and good sense. I go to the gym with people of all backgrounds, I watch kids playing together and I think, wow, how far we've come.
I know things aren't always perfect; there are still misunderstandings between people of different races/ethnicities in this culture, but I don't think people with common sense question that racial/ethnic prejudices are wrong and just plain stupid.
And I never had difficulty with gay or lesbian friends; we would agree to disagree if necessary; it was perhaps a bit more tricky with vehement pro-choice friends but still civility could be maintained and I felt like I could speak my beliefs. Or the issue of birth control.
But nowadays, I feel like if I say anything against the liberal point of view on these issues, people are going to lump me in with the redneck racists of old.

Or say that I don't care about women - which is pretty darn ironic, considering that I am one.
