I recently got into a bit of a fight on the internet over Social Justice blogs and erasure. Long story short, a blogger that I respect (much as we may disagree) argued that Social Justice blogs and sites that don't talk about the issues of disabled people are inherently bigots because they contribute to erasure. Which, valid point seeing as most SJ blogs and articles focus more on LGBTQ issues, race issues, and feminist ones, without inclusion of disabilities. Because there are disabled feminists, disabled GSM people, and disabled people of color, and even disabled straight white people. But we don't talk about them.
I tried to argue that not talking about disability issues didn't inherently make them prejudiced although some of them very well may be, but I totally stuck my foot in my mouth. Thats what I get for arguing with people on the internet on an insomnia bender.
