I suspect you've never hung out with enough different minority groups to understand the scope of difficulty. I mean FFS the Latinos vote against immigration, The poor vote against social services. Even when you run into a minority group that is doing things in their best interest, they're not inclined to stick their neck out for people outside there subgroup. Nobody else is taking care of them so they take care of themselves and they give no F's about the other minorities

The concept that all the minorities together aren't a minority anymore is true at some level, I think you've got a better chance of having white leftists stand up for them then them standing up for each other.
