A couple of sites that might appeal to the privilege aware you.
Microaggressions - Basically just pull this link out whenever someone says they don't think sexism/racism are big deals anymore.
The Border House - Very accepting site. I've written a couple articles for them. Thinking of writing one on Persona 4 for them. The comments section are home to some really good discussions, at least the ones I've read, and they're good about calling people on stuff when they fuck up, without being as dickish as I usually am. See: When I got called out on my use of a couple words in an article. For the most part, I enjoy instances of being called out because it creates learning experiences.
Anywho, thought those might appeal to you.
