Some people on here seem to have an analysis of issues around gender, race and other things related to identity which strongly resembles the analysis most posters have of class. For me, class is fundamentally different to these things becaues it is material in nature, all bosses, by definition, exploit workers, if they ceased to do so, they would cease to be bosses, but they won't because it is not in their interests to do so.
White people, for example, have nothing which inherently makes it more rational for them to group together to opress non-whites, the vast majority of white people have nothing to gain from racism and no good reason to seek to maintain it.
Not sure how well this is going to come across, I'm ill and I can't seem to type properly without having to go back and correct mistakes every other word.

Racism, patriarchy etc are methods of social control and as such usually work in favour of the current system. Their ideological content can make them become inefficient, in which case, South Africa for example, the iron laws of capital eventually bring them down.
There are material bases for this.
'Our' leaders profit from us and they use racial genealogical etc stuff to make us think that we are best off with them. When two groups met in the past forms of nationalism etc were necessary to maintain the original group. People need an identity and the best way to construct it is by creating an 'other'. It is hard to define ourselves, it is easier to define ourselves negatively against this other.
In terms of patriarchy, I think that by giving each man a 'woman to oppress' we provide a safety release. Control of marriage etc, means women can be used/exchanged etc. Patriarchy commodifies women.
