Trans people get both deliberately and accidentally misgendered all the fucking time. They're subject to ongoing legal persecution and discrimination, and people barely give half a shit, but someone dares call a straight guy gay, and the internet suddenly needs to come out in full force to defend the rights of the poor, discriminated straight men who have it oh so hard in society, and literally compare it to the plight of a trans person getting misgendered.

Equating misgendering a trans person and calling a straight person gay is like equating calling a recent white south African immigrant a Boer and calling a black south African the N-Word. Just because both are shitty behaviour, doesn't mean they're comparable.
