Are you only talking about high fantasy or low fantasy too? If it's just high fantasy, off the top of my head:
For fantasy only being for men: You can maybe talk about how the fantasy genre is flourishing in YA, especially since the genre was created as a place where they put all the romance novels that are about teenagers and oblique about sex. It used to just be Tamora Pierce, Mercedes Lackey, Diana Wynne Jones etc. are what young girls got, but now there are a lot of other authors. That said there's an argument to be made for the fact that there's a certain ghettoization of fantasy with female main characters into YA which a lot of people see as "not real fantasy."
Another thing, one of the main reasons people talk about how a lot of the fantasy genre is set in faux Medieval Europe is that it's long been one of the reasons for people to defend the lack of racial diversity in the genre. I wonder if it would be missing the point to say "look fantasy is diverse, this is set in a faux Imperial Chinese setting" when these stories are very much the exception and not the rule. And also to say "diversity" but not talk about racial diversity.
Also, I know people have been recommending Chinese classic novels like Journey to the West, Madam White Snake etc, but the criticisms you want to deal with largely levered against Western fantasy novels so idk if I would use classic fiction from other countries.
