Oh, yeah, ignorance is alive and well and continues to thrive in some pockets--er, brains--in 2011.
People know what they're told. My husband grew up with parents that were, and remain to this day, unabashedly racist. He had to unlearn that on his own, because it was the family culture he grew up in.(Fortunately he unlearned it before we got together, or that wouldn't have happened.) I have heard his parents say things that have made my hair stand on end, and have tried to politely correct it, to no avail. Basically, with them, if you are not a skinny WASP, you are contributing to the ruin of the country. When my husband took our son to visit them a few months ago, he made them promise to 'behave' before he would even buy the plane ticket. (Even when I've explained to them repeatedly that my adoptive dad's family were refugees from the Phillipines during WW2 and that I would have been very sad not to have my dad, his family, or my sister in my life, they still rail against "the mixing of the races". sad sad sad.)
I also hear plenty of ignorant remarks here in Portland. People saying 'that's so gay', 'that's so retarded' as derisive terms. "That's so ghetto" was one that I hadn't heard until I was at a prenatal water aerobics class-- one woman would also talk about 'going to get ghetto food', because apparently she didn't know the word "burritos" like everyone else did.
And please don't get me started on 'They only voted for Obama because he's black'. To me, that is a reflection of the speaker's prejudice and fear, not mine. Speaks volumes. I also don't like being told why I supposedly voted for someone, which demeans *my* intelligence and is presumptuous, to say the least.
So, yeah, ignorance is alive and well.
PS: and "oh, why do you think that?" is always an easy question to ask when challenged by moments like these.
