I hear you! And people saying AAVE is ableist need to get a life. Every language has words that are offensive in other languages. Every language evolves as public tastes and standards change.
The Lizzo bashers just like to hear their own voices. They're probably not even disabled themselves, and they've probably themselves made life harder on disabled people at some time or another in their lives. They just want to get attention by bashing on a plus-sized Black queen who's got more beauty, talent, and smarts in her pinky finger than they got in their whole church!
