This is the sort of vague "argument"-crafting I expect on Twitter but not on HN where you have unlimited words to make a point and add understanding to the world.

I googled "jk rowling gender critical" and all I see is a great google query if you want to find articles about how supposedly transphobic she is (without explaining what was specifically transphobic about what she said). If you're going to say someone has admitted to being part of a hate group, why not help us out and provide us some links?
