Yes, but you can clearly see a woman in her profile pic, combined with a girl's name, on a trans instance, and if any of that gives you pause enough to check her profile, you'll find it says, "sapphic. hater of capital letters. bunny and cat mum." Just because some random guy somewhere goes by KD does not make it ok to misgender someone who is very obviously a woman.
Whoever downvoted this, come out and say it my face, coward. Fuck transphobes.
The point is that it doesn't discredit the original criticism. The guy in the comic is trying to shift the focus from the systemic level to individual consumer habits, and to discredit anyone who doesn't adhere to perfection. This is a common tactic the right uses, and no matter what level of ethical consumption you do they'll either still say it anyway or switch to characterizing you as an extremist or some other tact, for instance, the various tactics used to attack vegans and veganism. There is good faith criticism to be made regarding ethical consumption, but there's also bad faith criticism where it's used to discredit legitimate criticism, which is what the comic is calling out.
