China is kind of notorious for being the place where you can find internet trolls for hire for cheap.
Reflexively associating people & things you dislike with an ethnicity is a form of hate, and you are doing it. After all, America has plenty of – hell, I’d argue more – easily bought trolls available, and yet I don’t seem to see a whole lot of people bringing up their nationality so much, assuming they mention them at all.
And I’m not going to ignore racist statements just because pointing it out causes tension.
My guess? The couple wouldn’t bring any guns out to begin with, mostly because MAGA protesters would be white.
Liberal communities have plenty of racism. It just happens through ignorance & a lack of thinking instead of direct malice.
