Yes. You are absolutely free to not agree with methods some people employ for a cause. My main point is that to support Black Lives Matter does not make you militant just because some are.
At the core Black Lives Matter is about equality and about taking a look at why a certain segment of the population is disproportionately targeted by police. I support that.
However, that statement about BLM isn't correct. If you look at the true statistics and not listen to the media and Farcebook posts, you'll find that "disproportionately targeted by police" comment is wrong. And, BLM is a socialist group, perhaps even outright communist and equality is the last thing they want. They seem to want more and more, based on what we are seeing with their protests. I remember seeing a clip of them marching somewhere, crying out, "Pigs in a blanket, fry them like bacon."
