How about us white folk start being thankful that we don't need a movement?
I'm grateful to live in a country where traffic police don't carry guns, where there is no second amendment right to bear arms, where mass shootings are a rareity, not a daily norm. That being said, I'd be absolutely stupid to believe that racial profiling doesn't happen. Of course it does, and not just to black people.
#blacklivesmatter is important. When can you recall a white person in American being killed for selling CDs or cigarettes, or reaching to provide his ID like he was asked to do, or for moving lanes without signalling, or for having a broken taillight?
Try saying "they should comply with police" or "they shouldn't resist arrest". Did you see Philando Castille? Did you see how Eric Garner said 11 times that he could not breathe? Did you see that Freddie Gray's legs were broken as they dragged him to the van? Did you see how police had restraint of Alton Sterling's arms and hands? Did you see the way that Sandra Bland was physically pulled from her car?
