"It just is"? Seriously? You can't explain anything with "it just is", let alone a controversial subject.

I don't know what other kinds of vapid reasons the parent was referring to, but many are just as bad as "female". There's the obvious ones: racist, homophobic and transphobic justification for example, but also less common, also harmful vapid justifications. Dismissing someone's idea because theyre an ex-convict is a good example. Or on the basis of their age.

These are all quite bad, even if not completely equally so. I'd humor an argument that "female" is the worst of these simply because there are a lot more women than ex-convicts and members of a gender or sexuality minority, and therefore more people who could potentially be hurt.

But not "it just is".

That's the closest I've seen to someone admitting that feminism is a religious belief system.
