Having interacted fruitlessly with lots of GC people online I can confirm it is always like this, even with those who style themselves as moderates*. Its always relentless misinformation, and as soon as that information is challenged or interrogated its onto the next thing, because the so called 'facts' dont really matter, the intent is to keep those supportive of trans rights permanently on the back foot whilst hoping that some of the misinformation sticks with those observing the discussion.
That's why it rankles when people say GC feminism is just a bunch of concerned women with a few bad apples who are genuinely transphobic. That is not my experience at all, and whilst there are obviously women on here who criticise gender and do have sincere concerns, those within the GC movement who are active, either online, or in real life as part of organised groups, are pretty much always like this. It's a slew of misinformation and all precision targetted to damage how society views trans people as much as possible. That's why I believe that rising crime and abuse of trans peoeple, and if the increasingly frequent social media reports coming in indicate anything, quite possibly gender non conforming people as well, is to some degree the responsibility of the GC movement. Having said that the right wing press should probably take the bulk of the blame (not that you can see much difference between the two camps when it comes to trans and even LGBT matters these days).
*Obviously quite often its much worse, and very quickly descends into open abuse and accusations of being an abuser, paedophile supporter etc.
