The bit that’s fascist is that birthright citizenship is guaranteed in the US Constitution, and the current administration is openly flouting it.
The debate is over what "subject to the jurisdiction thereof" means, it's misleading to simply announce it's guaranteed - the whole legal argument is over whether it is guaranteed.
Let's not pretend all assertions are equally worth entertaining. Maybe it's "misleading" if you're Stephen Miller, but every court case where it's ever been heard and the legislative record at the time of adopting the 14th amendment show that citizenship is guaranteed. The Trump administration hasn't even raised it in appeals!
