tbh there's a growing problem in leftist spaces where it isn't clear where straight cishet white men fit in to it. Yes it makes sense to have certain spaces more geared towards, and to an extent exclusive towards women, people of color, queer people, and any combination there of, but it's also necessary to have something for one of the most politically powerful groups in in society. In general actual leftists are better about being open to anyone, but liberals and liberals pretending to be anti-capitalist can get very suffering-olympics about it.
