For those who don't realize it, "All Lives Matter" and "Blue Lives Matter" are basically **RACIST** TROPES, started by WHITE SUPREMACISTS.
The idea is to "twist" "Black Lives Matter" back on Blacks by basically saying, "YOU BLACKS ARE THE RACISTS.--*ALL* LIVES MATTER."
The white supremacists realized that MANY whites would PICK UP on those, NOT realizing their UNDERLYING intent.
