I have never seen the word “woke” used unironically and TBH I’m not sure I believe that it actually exists.
I have, but not for about a year.
It’s probably not very accurate anthropologically at this point, but it is incredibly useful, as a short encapsulation of “all those things that social-justice-y folks aspire to and demand of others.” I can’t speak for anyone else, but my usage of the term isn’t mostly ironic, it’s “I need a word for this thing and don’t have a better one.”
