Racism and Anti-Racism

Several questions have been bough to my attention, by a person whose name I shall not mention to preserve their privacy. I have decided to throw my hat in the ring and explain my poorly-thought-out position on this issue. I would like to further preface this post by saying I live in an ethnically mixed, but racially homogenous (specifically 99.1% were "white" in the 2011 census) enviroment. And that will be using the word "racism" as a catch-all for both biologically and nationally focused biases.

I don't see how i can be being racist against my own kind.
This is actually a misconception one reads a lot on the internet. People will often say racist things about their own people and then claim they're not racist, because, well, how could they be?

To answer this we come to our first stumbling block: Racism is not a Yes/No check-box, it's a scale. One person might want to kill everyone who isn't his exact ethnicity, while another has no black friends (but is otherwise equally courteous to everyone), despite black people representing over 15% of the resident of his neighborhood. Which one is racist? If you answered both, you are correct. If you said guy #1, you are also correct. If you said neither, I really wouldn't want to meet you in a dark alley. And, of course, if you said guy #2, you were guessing at random. The point here is we consider people to be 'racist' if they are more ethnically biased then some set point (usually just above how racist we ourselves are).

Back to the question: they aren't usually very racist, but they are more racist then none- towards their own people. This isn't much of a problem for them, however there have been very serious cases of this in the past, where vast number people would actively hate the fact that they were born into one ethnicity, instead of another ( like wanting to be British instead of Indonesian, or Han instead of Manchu.) The point to take home from this is: ethnic self-hatred is a very real mental disease. Remember: thinking your race/ethnicity/gender/age/sexual preference/hair color/etc. is wose then others is just as racist as thinking it's better. They are all equal in the end.
