Well... all I can say is.... if you are or identify as "white"... and if you were not already "wacist"...
you probably will be before this anti-whitey-police idiocy is old news.
Personally... I'm getting really tired of seeing black thugs resisting arrest, running from police, attacking the cops trying to arrest them, and then getting cannonized for having been "stopped" by police. This is the literal definition of madness. And I admit...I'm getting pretty mad.... 
As long as there is a racism, nothing will get resolved. Accusing people of being racists when they aren't only creates the opportunity for racism to spread.
We have a local organic farmer who also hosts entertainment; primarily country & western. The owner called the BLM movement a hoax and stated that "All Lives Matter" and held an event ... large protests are now under way surrounding his business. He is now labeled a racist. Go figure. How is saying "all lives matter" racist??
So it's All Lives Matter v. Black Lives Matter, but the people who are promoting for all life, are the racists! You are correct, if you weren't racist before, that door is definitely swinging wide open.
