There was a thread title I recently reported, as it had the word "dumb" in it. It remained unedited and completely filled up, so I assume that up to 1000 people were fine with the term. Mumsnet also said that the word is in common parlance, so wouldn't be deleted. Why is it considered acceptable to use disabilities as a slur still? We rightly condemn sexism, racism etc, so why are disabilities seen as fair game?
