It’s over having a community wide hard line on pronouns. Even if a suspected troll is using neo pronouns (or any pronouns frankly) that’s not a license to misgender them.
The user that sparked the recent controversy (drag) has a history of being pretty volatile/offensive but that’s still no reason to compromise on neo pronouns.
I for one would rather put up with someone ‘trolling’ while using neo pronouns (until the inevitable ban for saying something shitty) rather than tolerate anyone getting misgendered in a trans-inclusive space.
I think the first two as commonly used are more homophobic, the latter more misogynist
