and since criminalizing masculinity is a goal of feminism
This is factually incorrect.
Feminism is about equality and freedom of choice for women. Feminists in the real world are everyone who supports this, whether they apply the label to themselves or not.
You vehemently perpetuating false information is part of why some people think feminism is bad. Stop.
So that makes all feminists bad? I would argue that JK may have actually been a somewhat good person right up until she stopped being a feminist and started being transphobic.
