I'm not sure what you mean by "removing the vocabulary of war".

> But personally I don’t see a lot of downside in the attempt to better our world.

I see tons of downsides; people are losing their livelihoods over the mere appearance of impropriety defined by activist narratives. Putting so much weight into these types of things may unexpectedly cause us to view social justice in the hollow terms of performative things like word choice instead of actual equality, etc.
