As a female gamer who has run the gambit, LARP, table top, miniatures, video games, I have not had the experience of not belonging or feeling like the odd man out. My current table top game has an 50 - 50 split, if you include the GM, of men and women. I've experienced more sexism in church, the SCA, and college.
I read about this exchange last month and tbh, there is more to the story than is posted here. This woman actually was forced to tame down her initial trash talking of him and gaming by her editor. The community was not kind to her on Twitter, but neither was she kind to members of our community.
