Racism

I have very strong views on the topic of racism, what i'll never understand is why people do it? what do people get out of it? Previously talking about the topic of shop lifiting and discussing why people do it, they get a joy out of it, but what joy is there about racism? Nothing, I'm sure many people have been victims of racism, I have and it's not nice at all, Racism actually ruins peoples lives, black white brown? why does it even matter? I have posted a link below that looks at racism from a global persepctive.
http://www.globalissues.org/article/165/racism Recently many issues have arised particulary locally where fights have taken place, people have been beaten up just because of the colour of there skin, parties such as the BNP and EDL are ones who only want white people in this country, Its understandable that alot of illegal immigrants are entering this country but innocent people are getting hurt because of Racism. I have posted another link below that is a recent article from the BBC about racial attacks that have arisen. http://news.bbc.co.uk/1/hi/england/manchester/8577777.stm
