I recognized that ugly anime avatar immediately as one of the TRAs from the r/PCOS clusterfuck. This dude was telling the women there to address each other as ovary-havers, and when it was pointed out to him that not all of these women have their ovaries, he suggested that something like "hello, current and former ovary-havers" would be an appropriate greeting. When it was pointed out that this was dehumanizing, he countered that words like "ladies" and "women" were dehumanizing to trans people. Both here and on that thread, he claimed that the words "female" and "male" were effectively hate speech against trans persons. And he's been going around telling people to watch what they say, citing the Equality Act, which is not law, as though it's going to punish people for transphobic thought crime, which it wouldn't. I really cannot tell if these are real beliefs or if this is just a particularly dedicated troll, but most of the fellas on SRD aren't having it. (By contrast, at least one person on r/PCOS took him seriously, thanked him for the information and promised to educate herself. Sigh.)
