You’re conflating multiple things here. Protesting is different than rioting and looting. I don’t think Americans have a problem with people protesting, it’s the rioting and burning down their cities that they don’t like so much - go figure.
The public has every right to be suspicious and push back against BLM. Their demands are hot garbage. Even Democrat leaders don’t want anything to do with their #1 goal “defund the police”.
What exactly is the point of supporting a group when you don’t agree with their ideas? Isn’t that a tad disingenuous?
To be clear I 100% agree that every black life matters. I don’t think the group BLM really cares about black lives though. They should have went with their first choice “black lives only matter when killed by white cops” or BLOMWKBWC.
