Supporting one issue publicly does not mean you think it's more important than every issue you don't support publicly.
That was literally the whole thing of "inclusive language" right? It wasn't about what the words actually mean, just how people felt about them. If they felt the word was discriminatory, then it should be fixed.
If you're going to throw up banners on every JS site for one cause and not another, you're saying very loudly you don't care as much about the other. You, under the logic of "discriminatory language" even be engaging in discrimination.
There is a big difference with war and people being systematically killed and a potential unjust legal system. War is obviously many times worse in every aspect and I think it's hilarious on what these people publicly support and what they don't.
It's hypocritical, unfair which makes it a big irony since that was what the BLM movement was all about (unfair treatment).
