Lol, have you been to East Asia? Getting told to fuck off isn't exactly a hard thing to provoke in Asia, it's not something that only happens in America.

You claim yourself as Chinese which means you know best about all Chinese culture right? Which is such a common Chinese xenophobic tactic.

Almost as common as white people explaining Asian culture to Asians on this social media platform. I've been lectured to about my own culture by European and Americans who have never left their own countries.

But at the same time you’re so disconnected from your own culture you feel the need to share you and your own parents ethnicity

My dude..... Your ethnicity doesn't change just because your parents migrated to another location. The fact that you can't recognize stripping someone's ethnicity away from someone because they weren't born in there families homeland is just another form of forced assimilation, and is incredibly racist.

Again, utilizing an acronym to other delineate someone from their ethnic heritage is disgusting. Especially considering that I doubt you've ever had to deal with navigating the social stratification of being an immigrant.

Accosting a Chinese person for not being Chinese enough is just about the most 4d chess move of racism a white dude can pull off. Congrats.
