I don't claim to know much more about them than this, but from what I've gathered, they don't seem any worse than the congressional black caucus or feminists, just for a different group.

If you haven't noticed, the only institutionalized discrimination in the US is against whites and males.
This has been the hallmark of White Supremacist theology....
