Umbrella Term is a optimistic description for something so nebulous and used so frivolously. It is more commonly used as "anything I don't like is woke" and "any opinion that doesn't match mine is censoring me."

Note how the definition there doesn't match any of the three definitions people gave me here, and none of the three here seem to match each other. Also, as your link says, the definition seems to have changed drastically in the past few years, so I can't even be sure that the link has the most up-to-date definition.
So, I was asking someone who seemed to be very passionate about being "against woke culture", to hear it directly from them. This is a conversational site, I figured it'd be fine, but seeing that my question is now downvoted I guess I need to better learn what conversations and questions are appropriate here.
