I downvoted you for the "marketer/enthusiast" comment. I think that was out of line. Deciding whether she's an engineer or a marketer is not up to you, it's between her and Github.
That said, feminism describes lots of different things, and I think she was addressing a broad group with that first statement. The sooner you realize that not all feminists have the same agenda, the easier it will be for you to understand what's going on.
