Reddit mentions of The Disability Rights Movement: From Charity to Confrontation

Well, if you're posting here then you know something about it. A lot of it vaguely mirrors Women's Studies and Critical Race Theory or even Queer Theory. The science of oppression if you will.

Some basic things to look into are issues like People First Language, it's very popular among Social Justice types but it's good to ALSO be familiar with dissenting opinions like that proposed by the National Federation for the Blind.

Also, studying the Disability Rights Movement is pretty key, but you have to watch a lot of early documentation of it really sidelined the contributions of women (Intersectionality ahhhh!!!!). This book was pretty helpful to me.

One of the bigger points of history here has been the creation of the ADA which plays a large role in that legislative definition of disability I mentioned earlier. However, the ADA grew out of the Rehabilitation Act of '73. Nixon tried like hell to gut it but there was a national protest by people with disabilities at government offices across the country which, for its time ended up being one of the longest sit ins in a Federal building that had ever occurred. Of course, the wiki article mentions none of this, but you'll find out all about it in that book I linked above.

Also, understanding the Social Model of Disability is important. Those are some quick things to get you started.
