There's a big difference between raising honest, thoughtful points about social justice issues (even forcefully), and using those same issues (superficially) as a cudgel to marginalize your enemies and increase your own social power (and note that those things don't have to be happening at the same time).

These days I see a lot of both. I also have no idea what happened in this specific case, and at this time I wouldn't be willing to take a side.
