We don’t say “woke” as a weapon to shame you. We say “woke” to refer to the thing. The word will only stop “working” if we can no longer use it to mean what we mean when we say it.

It’s not like some kind of drug there’s going to be a tolerance buildup, or a weapon that runs out of ammo. The way we use words — to communicate by referring to things — isn’t something that “stops working” over time.
