There are an endless number of causes one could "black out" for. But they just so happened to black out for the one with a pressure campaign and mob backing, that has intertwined itself with American national political ambitions?

The emotional blackmail of this movement will probably be its undoing.

Imagine feeling "emotionally blackmailed" into not supporting extrajudicial murder...

It is easy to support that stance. Or even perhaps just stopping extrajudicial murder by police as a whole.

Go look at the official BLM list of goals - they are advocating to abolish the police, end capitalism, abolish the western nuclear family & several other far left, badly thought out, unsupportable concepts.

Worse still, the same campaign has spread to the UK, unfiltered and unchanged, despite the fact that we have almost zero people killed by police outside of terrorist attacks, our police don't carry guns, and due to our government's austerity policies, they're woefully underfunded.
