My sample size is small but I don't know any individuals who admit to sending money to BLM, even the ones who did slackivist crap like changing their profile picture black. I only heard of corporations donating. If these individuals were sending money it they'd be virtue signalling it, like that guy who set up one of those "birthday donation" things on Facebook which I didn't see any of his friends actual donate to either, the sole donation listed was his own.
