It didn’t in 2015.
You are seeing white people joining in 2020, because in the age of Trump, we have become a more integrated society.
Plus, we have something here that was clearly a crime, and nobody is arguing about it. It is easier for both sides to be together when nobody is trying to claim things that didn’t happen.
This is why the left is sending in people to cause trouble, because they need us divided.
Excellent point. Far too many times the leftists Scream police brutality over every little incident even win the video clearly shows the use of force was justified. In this case everybody sees it wasn’t justified, however they will not let the narrative fit in and keep protesting as if the majority of people disagree with them that what happened to George Floyd was wrong.
