Not going to say much on what's happening in the OSC, but heavily lambasting people without actually talking to them about what they have done wrong, especially if they admit didn't know much about the context of the issue, is not helpful.
You can at least educate them about it. That's fucking more productive than blasting them on your account. Also, since this is on the topic of racism (and you know who's awful video as well), I feel the need to say this:
If you are white, don't butt in on an issue that harmed BIPOC. Just listen to us, or at least be supportive.
Also, for white allies, you don't need to callout every single other white person for their mistakes. I honestly rather you try to talk to them first to help them understand. I have concerns if you do more calling out over actually having a conversation.
You are not helping if you do this.
If other BIPOC are trying to tell you that you are not helping, listen please.
You don't have to hit people over the head for them to learn. You really don't need to. Just at least, reach out to them. Please.
You can hold people accountable and help them understand what they done wrong at the same time!
With this said, I highly suggest watching this video by
F. D. Signifier on how not to be an ally:
