The point is to strawman their argument because she can't actually argue against it.

I bet she wouldn't jump at the opportunity to get raped and carry the baby to term! How hypocritical! /s

It is actually worse than that.

E.g. if you want to help starving children, does that mean you want to live in e.g. north Korea?

To me, it seems wanting to help e.g. starving north Korean children, without wanting/planning to get any reward like seeing less starving children on your way to the supermarket, makes you a better person.

Probably that they wouldn't want a life under Hamas which, yeah they probably won't but I don't think they're arguing that it's the best place to live to begin with.

This is an incredibly common thought among the reactionary right and I think it literally boils down to them thinking about everything like this like its a game or a sport, so when you support a side like palestine they can only comprehend that you think Palestine is a great country and you love everything about it and fully support all the people there and everything they do. Because they literally dont have the mental capacity to view things in anything other than the most binary black and white as possible.

My initial thought was “huh? Of course they wouldn’t want to go to school in Gaza…”

The most generous interpretation of her remark that I can come up with is that she’s saying all these kids want a free Palestine but wouldn’t be brave enough to do the freeing themselves.

Or she’s implying these kids wouldn’t want to go to school there even if it were free because, let’s face it, <something racist/classist/both>

But there are much clearer ways of expressing either thought, so it’s anyone’s guess.
