You can't both shove Disabled people out of offline spaces and then say "online discussion of how not to be a harmful person isn't praxis".
I mean, you can but you're being an asshole.
And for many Disabled people, those offline spaces were never accessible. It's not just masking.
I don't know that folks who haven't been paying attention realize how extremely powerful social media has been for allowing Disabled people who are otherwise isolated and excluded for so many reasons to connect and share ideas and be heard.
I hate it when people lie to my face to save their own.
It's like, sure, there are discussions to be had about posting-as-praxis, but so precious few people seem to be approaching them in truly good faith and with a person-centered, trauma-informed framing.
