That tournament was run by IeSF - an organization that is grossly incompetent and disconnected from reality. They have very little traction in the eSports scene and are in no way representative of eSports as a whole.
Make of that what you will. I, for one, would rather not be grouped with them.
Disclaimer: I support women-only events. I think they're an important tool in helping decrease the immense disparity when it comes to men/women in eSports. I don't think they're necessary because women can't compete with men, but I think they encourage more women to participate.
It seems like you have an axe to grind.
