As I noted in a recent piece, antisemitism is on the rise globally and in the US; even the Pentagon is doing an internal review, so the likelihood of some deployed to the ME being white supremacist themselves isn't nil.
On the other side, it's normal to be shocked to hear someone else feels unsafe. "Among us?! What did someone say?!"
But it doesn't have to be explicit. It usually isn't. When real-world trauma becomes internet debate for others, it's *all* radioactive. Taking space is survival.
