It ain't half racist mum?

I love my housemate to bits but at times his behaviour is a bit worrying! He's your typical white boy just out of uni, clever, 'damaged', drinks too much, parties too much and carries on like he thinks he is still at uni. He's great fun and extremely helpful in many ways, giving advice and even helping with my uni work at times. Problem is he is 'typical' in every sense. Perhaps this is what Barack Obama so uncharacteristically failed to eloquently allude to in his speech on his grandmother being a typical white person. What is a typical white person? Well it is difficult to say, as i am not white. My step-mother was white, my brother is half white; does that mean he is half a typical white person? It is indeed a difficult question.
My reasons for this post are as follows. Friend one (who is aforementioned housemate) goes clubbing with friends (i should mention i was asked to come but couldn't as i couldn't afford it) and meet random people who turn out to be white South Africans. Friend one invites them back to his flat (which is mine too) and they carry on with their partying all through the weekend, which i do not mind. I do not interfere as i am wary of white South Africans, and with good reason it appears. My housemate makes the oddest statement (as he regales me with stories of their mad bank holiday weekend). He says, "I told M (who is a mutual friend) that those South Africans are racist as f*** but they were good fun though!!". I was gobsmacked, even though in light of what mr Obama's underlining message was trying to say, i should not have been. Trying to take the steel out my voice, i replied "How fortunate that you are able to reconcile the dichotomy to their existence". He mumbles something, and leaves. This mutual friend goes away this weekend for a while and wants to go out with the gang. He has asked me on a few occassions to come out with them and i had previously agreed but if those SA's are coming as well, good manners out the window, i will refuse to go!
Friend two at work. Pleasant, funny, charming. He however makes fun of Indian accents betrays uncomfortable ignorance of the world outside Europe and America, which is often unsettling. He is young, white and male. This is not to say that we do not get on swimmingly, we do. There is however a problem.
Barack Obama came under fire recently for suggesting that all good white people are a little racist (invariably thats what he meant). whilst his delivery was questionable, i understand what he meant. It is nearly impossible to grow up in Western society and not be conditioned into believing the white supremist ideology that is prevalent in this part of the world. I will not go into detail about how wrong the ideology is as it would be a waste of my time and anyone reading this. However, It is funny that many should subscribe to it. The idea being that white people have created advanced styles of government, technology and so on. Agreed, but what about the individual? My housemate has graduated with a lower second, drinks and parties and isnt in a great job, so how does he qualify as great? This is same for mostwhite people who subscribe to this ideology. As was quoted in the movie Irobot where sunny (the robot) is confronted by Del (played by Will smith who was in the movie) on his not being human. Del shouts, can a robot paint a canvas or create a symphony like a human? Sunny simply replies, can you?
