Hey, I totally feel you, albeit in a different way. I feel erased by people who share my ethnicity because I can't fully share their heritage. I'm Mexican and was raised without being taught Spanish and without many minorities of any kind (the Northwest is surprisingly white in many places). I'm considered "white" for my mannerisms and the things that make me individual because I don't fit what is stereotypically "Mexican". People tell me that my English is very good when its my only fluent language.

I think one problem that I could conceivably see with your logic is that even if, numerically, Black Lives make up a smaller percentage of police killings, it is a higher percentage of the American Black population overall, then when compared to other races. I am making this claim based on the statistics in your post. This doesn't warrant anyone to tell you to 'check your white privilege'. Fuck them. And 100 years ago or whatever, you probably wouldn't have been considered white at all, and profiled the way brown and black people are today.

That, and Black Lives Matter, in MY mind, is more about highlighting the fact that Blacks in America are not treated equally in most circumstances, and that Americans are numb to the physical and psychological violence Black people face every day. It doesn't change the fact that you face those things, too.
