They’re used as anti-semetic slurs by the far right. There seems to be a proclivity to use the terms as applied to bug-eating politics, but unfortunately the term is simply too associated with anti-semetism and I think particularly given the current conflict it makes good sense to filter it.
Huh, I’ve only specifically seen it used as referring to Asian people or Chinese people in particular.
Though as some have pointed out, Sinophobia shares much of its DNA with Antisemitism.
I think the term is meant to imply non-thinking automatons, so that makes sense
