This is an incredibly dishonest argument imo. Ignoring the fact that Grindr saying #BLM while changing a policy doesn't mean "BLM supports it", it's an entirely different policy and situation. Grindr is a dating app that had a race filter. Not a video content website that lets users tag themselves by their race or sexuality if they want, a dating app that allowed people to actively exclude any and all members of a race they did not what to see.

Even if you disagree with what Twitch is doing here, you can't possibly suggest that it's the same thing as what happened with Grindr if you're actually engaging with this discussion in good faith.
