The Black Lives Matter protests are about systematic police brutality and racism. In the face of such weighty issues, it seems petty to talk about mere language, potentially even a drain on activist energy. Nonetheless, I personally find language to be a stimulating topic rather than a draining one, and it can be used as a lens to engage with larger issues.
The larger issue here, is the relationship between anti-racism, and Asian Americans. Anti-racism in the US has largely focused on anti-Black racism, and to a lesser extent anti-Latinx and anti-Indigenous racism. Asian Americans–as well as people of other ethnicities/races/nationalities–tend to throw in some nasty complications, mucking up the clean generalizations people would often like to make. For example, asking people to recognize their White privilege just falls flat when the audience is simply not White.
And you should know, I’m not deliberately trying to trip up anti-racist activists. It’s not a gotcha. It’s just a fact about me, that I’m mixed race Asian American, and my list of privileges is somewhat different. The differences are sometimes important, sometimes not.
