I think the reflex naturally makes sense, but from the people I personally know to be outspoken and definitionally feminist, it’s more like calling yourself a feminist says you explicitly side with the feminist cause. Sort of like saying you’re anti-racist rather than identifying as someone lacking racism, which is actually a farce when we’re all biased.

But I think the idea is that men should get the same lenience, i.e. just-feeling-wrecked-leave rather than menstrual-leave. The difference in having a baby should be that one needs medical leave too, in my mind.
