This is a tale as old as time. Oppressed groups are naturally conditioned to be hyper-defensive per the oppression they face, which results in lashing out against neutral parties, which comes back to haunt the oppressed group as oppressors can now point as their "inherent evil" and sometimes even the neutral parties will say "hmm maybe they ARE all crazy" and become oppressors themselves. In this case it's not even a neutral party, but someone who is part of the oppressed group theirself, being ostracized by their own community.
I'm reminded of the time that Contrapoints (Natalie Wynn, a veritable transgender icon) got cannibalized by the very community she seeks to advocate for because she confessed that the pronoun dance that happens in inclusive spaces can feel like a step backward for a newly passing trans person who wants nothing more than to be supportive of others, but simultaneously wants nothing more than to naturally and intuitively be referred to by their preferred pronoun without needing the dance. If even the champions of the community are going to be eviscerated for not treading lightly enough, what hope is there of recruiting allies from normie-space?
