Desensitisation begets it's own dangers. Being inured to prejudicial conduct increases the likelihood of dismissing it where it manifests more subtly, rendering it an even worse oversight for it being a conscious choice rather than a lack of familiarity. Add to that the potential for organised contentious groups to proliferate in the face of this self-imposed apathy. It may be that over-education creates more problems then none at all. Not that indifference and complicity are to be encouraged of course, but that perspective could become an issue where race is formally instituted as a universal baseline, via undue emphasis.
Race issues ought to be stressed as products of inequality. Not as opportunities for application where none previously existed. In other words, they should be reiterated as problems to be resolved. Not as conditions to be maintained into perpetuity.
Yay! Post alteration! Upstairs, too.
Other, because I really don't think it matters. People need to stop being offended at every little thing. If someone is genuinely ignorant of something, instead of being a complete tool by berating them, and shouting "racist!", people just need to tell the guy. Getting offended and butt hurt by menial crap is just as bad as the jackass who doesn't know [s]he said something offensive to that person.
I love the NSA. It's like having a secret fan-base you will never see, but they're there, watching everything you write and it makes me feel all warm and fuzzy inside knowing that I may be some person's only form of unconstitutional entertainment one night.
It all comes down to intent (conscious and/or subconscious) and perception, the old puzzle of how humans communicate.
There are folks who will ALWAYS hear racism from a person of another race, those who are flat out racist, those who don't want to be racist at varying positions on the path, and those that can be, at least for parts of their lives, past it.
The back of the bus thing is known about wherever people speak English and read newspapers. I'm a foreigner, to you, and I know about Rosa Parks. It's not an obscure reference. I've been to Australia and I'll guarantee you it 'jumped out at him right away'. The only difference between Australian and American racists is the ones in Oz don't hide or minimize or apologize. They just flat-out are.
