I partly agree with you, but to be fair, the O.P. does talk about how no BLM-related organization (not just Patrisse's) has stepped up to help those who are suffering from the loss of Floyd, and also talks about the "defund the police" slogan being taken literally and causing problems (and the slogan is a prominent rallying cry for BLM). The meta-criticism that it's a juicy scandal that the media would be all over if it was a children's cancer charity, but isn't getting any airtime, is also pertinent. So it's not entirely a critique of Patrisse et al.. (But it is too much of one.)
