It is a profoundly complex issue, and that's what makes much of this comment section so frustrating. Many of the arguments here are very reductionist and fail to account for detail or nuance. In this particular case, I have a hard time excusing the behavior of the accused interlopers given that this is a women's conference that has been a recurring event for quite some time and has always been a women's conference.

Lack of education or not, I don't think it's unreasonable to ask professionals to act professionally and refrain from attending events not intended for them. I think there's a significant amount of leeway being given to the men/foreign workers who showed up at the women's conference as if they cannot be expected to regulate their behavior in a professional context. It's the same kind of hand-waving and excuses that perpetuate the good ol' boys' club that the tech industry already is. It is irksome that people here aren't realizing that the arguments they are making about exclusivity or discrimination are the same arguments frequently used to excuse the misogyny and sexual harassment that is so ubiquitous in the tech industry to begin with.
