I see a lot more truth in the joke than racism. I once had a problem with my HP computer and I called their customer service. The rep was polite to an extreme but his English was spoken with such an accent (Far Eastern ) that I could not totally understand him. I had to decline his help and there was absolutely nothing racist about my decision.
I, for one, am tired of everything I say is challenged because of political correctness. As Neal Boortz says, "Anytime I disagree with President O'bama I am considered a racist, for no other reason."
I grew up as an idealist, but life taught me that I had to get my head out of the clouds and face realism.
