I can have sympathy for people desperate for jobs, and I can understand class warfare, and yet … once again something that women and enbys spent years and decades building up, is ruined because cishet men decided it was more ‘convenient’ for them to invite themselves into spaces not designed for them.

Couldn't this same logic be used by men to justify not allowing women into the tech industry in the first place? If someone of the wrong gender being around counts as "ruining" then men could say "once again something that men spent years and decades building up, is ruined because women and enbys decided it was more ‘convenient’ for them to invite themselves into spaces not designed for them." In fact I'd say something like that attitude really is what underlies a lot of tech industry sexism.

Gender-exclusive spaces often seem appealing to the favored gender, but they're really not good for anybody.
