I watched two wheelchair users break down in tears. Another took one look at dealers den, said "oh, fuck this" and left the con. I've never cut my losses and just LEFT a con, that I traveled from out of state to attend, because it was such a disaster and literally painful to try to navigate.

You could have avoided all of it. ALL. You chose not to. That was hostile. So I repeat, NO, you do not get to ride the coattails of someone who is actually making a difference and pretend like you're for any of it when you actively, knowingly, treated disabled attendees like second class citizens.
