There's all of this racism out there, it's everywhere and I know the invalid reasons as to why it occurs. There's so much racism in the world, but I'm not racist, because I know why it exists and I assimilate with other people that just bob their heads in agreement whenever I impart my wisdom on why, where and how many racists there are in my community and with our wisdom we can easily identify them and one day we will have implemented enough far reaching social policies that it will be impossible for racism to exist in our society.
So all of you people have worked out why there is racism (a few had honest answers that address evolutionary psychology) and that you are all non-racist (that's the implication in the tone of the posts, no one has been explicit though, granted). Then please click the link:

I saw other researchers that designed an implicit association test and they had, self-admittedly, taken the test hundreds of times and still couldn't do well on the test. These were professors in the marxist blah blah studies departments, you know the type, complete rejection of the biology department, everything is a "social construct, they make all sorts of ludicrous statements regarding race, racism, sexual dimorphism and history. The blacks in the video (activists) that took the test scored worse than the whites, despite being adamant that they were the most egalitarian, colour-blind persons on the planet (I knew that they were going to score badly when I heard them speak before taking the test, overstating your case just screams projection). The justifications and excuses that they reached for after facing the reality of their results were simply logic defying.
But not everyone, sadly, was raised to believe that taking this risk and pushing comfort zones was worthwhile.
Who here is racially and or culturally a majority in the country that they are currently living in and yet choose to live in a neighbourhood where they are a minority? and be honest. The people that dogmatically pay lip service to multiculturalism are not the ones that pay the consequences for it. Much like Howard Dean proclaiming that "some people have a problem with diversity", now I don't know where he lives, but I bet it is both gated and racially homogeneous.
The root of in-group prejudice is the simple fact that it's easiest to feel comfortable around people who remind us of ourselves, in any way.
It's a survival mechanism, always has been and always will be. If a significant percentage of individuals within any ethnicity or culture can convince themselves that suppressing this instinct is the only way that a person can be pious or worthy of an opinion, to atone for some misplaced guilt, then this ethnicity will disappear in short time. You know why? Because all of the other groups have the same biases and are playing the same game. Unilateral suppression of prudent in-group association leads to cultural and ethnic suicide (this doesn't necessarily even need to be with bloodshed - don't think only literally, the gradual subversion of a culture and an ethnicity's society does the job also).
Also, please don't think that "survival" in the context of evolution refers to the individual, it functions on a genetic level. Bodies are just the machines with which genes compete (or fight) with each other.
