On BLM-- To qualify as Terror, the perpetrator(s) seek to influence the behaviour of others. The terrorist has an agenda-- and perhaps an ideology or manifesto.

Terror groups seek to influence others 'outside' the group to act on their behalf-- therefore a domestic group like BLM can claim their innocence.

The targeted murder of 5 police officers in Dallas last July was such a BLM-inspired event.  Is that terror? 

Of all the suspects who are killed by police in the U.S. each year, 41.7% are white, 31.7% are black, and 20.3% are hispanic. Therefore, it should be White Lives Matter, then Black, then Hispanic-- in that order. Of course this is absurd.

More than a few protest movements have morphed into terrorist organizations in an attempt to accelerate their agenda via intimidation.  I fear this is happening with BLM.
