Totally agree with your view of how things work on a higher scale.
Isms will always exist because not all of us are equal and we will never be; and I'm not saying that with a discriminating tone, what I mean is that you have to be completely retarded (excuse me, but it's true) to actually believe and state that we are all the same. We all like different stuff, we all have different ways to achieve our goals, we even have (VERY) different moral foundations to asses whether something should be right or wrong.
On the other hand, most of us are used to live under the terrible premise to puts oneself (and thus, its kind) before others. Put these two facts together and everything that has happened (and will continue to happen) throughout our history becomes obvious.
