At first a handful
'CCP' - 
'illegal alien' or some variation of it -
'Death to Arabs' (edit: it's not a shibboleth but Israelis can really go fuck themselves) -
'suicidal empathy' (popularized by the likes of Gad Saad) -
'purity tests - oh yeah? here's a pell grant tests a la Kamala
will add more if I feel like it
Personally, I can't wait for the about-face in 5-10 years when US xenophobia/propaganda rhetoric softens on China and dipshits start saying things like, "well that was under the CCP. The CPC are the good guys!" as if they are separate entities.
