brown vs. white

this deserves be a quite long blog entry, but due to time constraints (1:30 am) it cannot be.
Perhaps it is due to my german upbringing and the constant consciousness of recent national history that I am rather sensitive on this topic. but if I have no understanding for one issue it is racism.
Why does it matter what skin colour you have? why does it matter whether you speak tamil, arabian or cantonese as a first language? IT SHOULDNT. but unfortunately I find it still does. People clump together in national or cultural cliques. It "feels like family". Any non brown, non chinese non whatever are not welcome because you cannot have a say in the language, food, religion, or...? Its all something you can learn about. Further, its something you should spend your time learning about, because it makes your life more interresting, and will make you more interresting.
I actually am not invited to events of friends because I am not indian, or at least asian. I was asked several times if i really wanted to perform in a show by the indian society. How can you even come up with such issues? I'ts quite outrageous. And this is happening in one of the most international metropolitan areas of the world.
If everyone draws up the fences, no wonder you get treated differently, if your heritage is that of a minority.
