Is it part of the bigger picture that all lives matter or is it exclusionary meaning only black lives matter?
It’s a protest. Black Lives are being ruined or extinguished by the government. The Tea Party Protests were started as protests against government.
The protests are not against all government, only against abuse by government. Government isn’t the only problem in America but it’s the major problem. Trump is popular because government has become far too intrusive and abusive. That’s the point of #BlackLivesMatter.
Black people are calling attention to police abuse of black people. Do police abuse white people? Of course. So do prosecutors and judges. But #BlackLivesMatter isn’t aiming at other races. Black people are complaining about government abuse of black people.
