"this could be what set the student off" โ I doubt that: I checked out her thread before she made her account private and it's straight delusion aka "China is egalitarian, they're not imperialist, only evil USA is imperialist" etc. Besides, even with your framing of a situation, it's moronic to think colonialism happens only in Palestine.
On your second part about searching for "Muslim bubble": sadly I can't help on that, but Nithin Coca เฐจเฐฟเฐคเฐฟเฐจเฑ (npub14ctโฆkm94) is worth following. He may know more.
