Southern Poverty Law Center
Sometimes I look around the SPLC web site. Most of their work impresses me. Wikipedia has a long list of civil rights cases they've won. They fight for all kinds of groups. They've made the USA a better place by forcing some places to integrate. They're fighting against the horrible Arizona/Alabama laws that hurt our Hispanic citizens - that law didn't pass in Mississippi. Plus it's fun in a weird way reading their profiles of hate groups and seeing how pathetic they are. They recognize that anybody can be hateful - not all the profiles of racist groups are white racists. There's a few black racists in there too.
But, there's a dark side. They've written before how they think free speech should be restricted. (Link) I'm against hate speech, but outlawing it is a good way to get people interested. That's how human nature works. Plus, the SPLC is liberal to a fault - they think if you don't support Obama, you're a racist sexist homophobe. They think all conservatives, libertarians, etc. are extreme radicals and that liberals can't have any faults. On gay rights, I can understand that position, but they think all Republicans are racist. (Does that make Thomas Sowell, Herman Cain, etc. self-hating black people?)
So, one and a half cheers for the SPLC. I respect them a lot altho I disagree with them some.
EDIT: Sourcewatch has a mostly critical article on the SPLC.
