Here's how you can tell it's a scam. It focuses on a very small percentage, but highly visible issue. It doesn't have any specific goals, purpose, or point of focus. Compare that to the actual civil rights movement, which affected a large percentage of people, had a specific goal (voting right, repeal of Jim Crow, etc), and relied on Dr. King as a pivotal focus point for reform. BLM is only focused on keeping people afraid and angry, so Democrats can control how they vote. Another reason you'll know it's scam is that it will have no staying power. Once the puppet masters see that it's not yielding the results they want they'll move on to the next scam. Why do you think it blew up so big right before a national election, and then got real quiet when the Dems lost? It'll be a footnote by June and most people won't even remember it.
Remember all the noise about access to healthcare? Are people any better off? No. Why don't we hear about it? I wonder...
How to keep people stuck in their circumstances:
1) Identify a "problem"
2) Blame someone
3) Promise Vengence/Retribution etc.
4) Blame someone, say something about access
5) Repeat steps 3 and 4 ad nauseum.
6) Profit
You can apply that to drugs, poverty, education, healthcare, really just about anything you're not happy with.
what's the small issue you're speaking of?
