I mean, what you posted, what she said is exactly the truth. This thread is proof that we're a community jumping to apply the worst possible interpretation. The Contrapoints thread had several people calling her trash, claiming that either they were personally done with her or that her career should be done, claiming that she was revealing the "real" her. As far as anyone has shown, this is literally one mistake she's made, and it amounts to a lame, distasteful attempt at ironic humor directed at a transphobe by mocking their shtick. I'm not saying that no one can be offended by this joke or express disappointment, but a thread like this isn't just designed for some people to express disappointment. It's an invitation to share in that disappointment, to have it compound, to dogpile over any perceived grievance. People can joke "oh yeah, we're TOTALLY cancelling her, WINK" but I mean, if that's not the end result here, why not express that disappointment directly to her on twitter (which enough did to warrant the deletion of the original joke), rather than paint Lindsay Ellis with the harshest brush in a thread disingenuously titled "Lindsay Ellis' transphobic jokes"?
Honestly, I'm thankful for these threads because my first naive take was fucking dumb and this forced me to confront that. I thought the 'I identify as a comedian" comment was at least funnier (and my naive assumption was that it was thereby more appropriate) until I realized it's wrong on exactly the same basis as the basis by which Lindsay is being criticized. The only reason she's being criticized in this way is she's a somewhat pubic figure taken to reflect vaguely liberal and/or leftist attitudes and we generally expect these people to be more accountable or virtuous. And this doesn't erase her virtue it just presents her with a situation where the appropriate thing to do is acknowledge some degree of responsibility. Ignorance can be partly exculpatory but it cannot do all of the work.
