I have no idea why this is even a question, I knew BLM was bullshit right out of the gate, it was far too slick and raking in far too much cash for me to think it wasn't corrupt. It hasn't even been around long enough for my opinion to change that much about it, unless you want to extend the BLM umbrella to *all* civil rights movements regarding black people in the United States in the past decade or so. Which I think is pretty drastic.
I've already seen some people on both sides including events as far back as the OJ Simpson trial in BLM which is just ridiculous. The political landscape back then was certainly different as there was no mass internet use to facilitate the development of something like BLM. There's also the rather idiotic idea that the Great Recession and Occupy Wall Street should be included too, though since that's more of a liberal point of view I suspect almost nobody on this site feels that way.
If anything as time has gone on I've become increasingly suspicous of just about anyone discussing the subject, since the (justified) backlash against black people across America is providing perfect ground for controlled opposition groups to sprout. If there is any kind of larger plan in place regarding BLM, the next phase is presumably to encourage the creation and growth of white supremacy movements, which can then be used to justify a crackdown. At this point its impossible to tell if someone complaining about current events is telling the truth and expressing real frustration at the horror show currently happening on the streets, or if they're a media shill trying to feed into the narrative that white supremacy is multiplying out of control.
You quite literally cannot trust anyone anymore, on any side of the issue.
