Racism

Racism, by its simplest definition, is the belief that race is the primary determinant of human traits and capacities and that racial differences produce an inherent superiority of a particular race. People with racist beliefs might hate certain groups of people according to their racial groups

I hate racism. I don't understand it.
I mean, how can people hate other people, solely on their skin colour and/or religion?
especially someone you don't know.

My brother is racist. He doesn't like black people ( which he refers to as niggers and/or monkeys) and he doesn't like asian people.
I don't understand why he feels this way. I've tried talking to him. but he does end up being hypocritical when there's say, a black actor whom he likes, but he tries to find an excuse like "he doesn't look black".

People like him, who hate others just because they look different. it doesn't make sense to me.
To me, people are people. We all have the same things (body wise). We all have skin, organs, hair, voices etc.. so how can pigmentation, something natural, cause such boundaries?!

It's not as if black people or asian people were somehow less capable or more capable or whatnot. it's not as if they were somehow different on a mental scale. We all have different languages and ways of thinking, but it doesn't make use better or worse than others. they are just differences.

With uni, we have anthropology, and in the practicals we examine skeletons, and the other week we had to examine the skull in order to identify which race/ethnicity the person was.
It was so hard to distinguish between one or the other, because they are so similar and the differences are minimal.
On a purely anatomical level, humans are the same with only slight variations when it comes to gender and ethnicity, which aren't always distinguishable.
On a physical level (as in the parts we can see), humans are pretty much the same, with again, slight variations, like height, weight, hair colour, hair texture etc.

So, if we are all so similar, why do some people hate others because of a) something they cannot control, and b) something which is natural?

In my mind, it's pathetic.
