The ACLU has nothing to do with the formation of BLM.
The ACLU messed up by claiming the terrorists in charlottesville had a right to free speech.
If everyone in Charlottesville who showed up to protest taking down statues was a terrorist, then every BLM member is calling for the execution of Cops and is a traitor to the United States. Same logic. You don't know who those people are because no one was given the opportunity to express themselves in free speech that day.
In Tin Pot dictatorships you can just call citizens terrorists of the state and have them rounded up, thats why you can have a dictator elected again over and over again. In the United States there is a reason opposing views are supposed to be protected. When you say that you know what someone is already going to say before they say it then deny their rights to free speech, your no better than anyone who has ever put chains on someone else. You pretty much have the same spirit inside you.
