Blueberry - gender critical beliefs are worthy of respect in a democratic society.
However, if you believe that Maya expressing those beliefs has been discriminatory you should say how. Otherwise it's just defamatory.
You might want to take a look at Jean hatchets case where she's just won a case to the tune of £115,000 for people lying about her on the Internet. And, apparently, it has set a precedent.
I'm not a lawyer, and I have no idea whether or not publicly saying that Maya, since she won her case, has been discriminatory, would come under that precedent.
But, personally, I think it's a shitty thing to do, if you're not going to back it up.
