Deir Yassin sounds vaguely German (I don't know who they are), so I bet that's controversial. But the First Amendment clearly protects speech like this, so at the end of the day it doesn't matter if it's controversial or not.
Also it clearly says "America First, Not Israel", it does not say "America first over Israel". Stupid media thinking they can just change small things whenever they want.
Deir Yassin has been a massacre of Palestinian people (120 of them) by Irgun (a zionist militia) in 1948. It's quite a controvertial subject, as you can imagine.
