I think a lot of people on the left took on the label of woke. Especially after that childish gambino song. In an effort to be a part of a group.
At least that’s how I remember it happening in 2016 era political landscape.
How this nomenclature has remained relevant for this long is a mystery to me. And yeah sure you could say it’s been around since the 70s (maybe even before) but I think it’s gone through multiple changes in core meaning.
Either way. I think you’re correct in saying the group won’t be clearly defined. But one clearly aims to be a group and the other is being told they’re a group by outsiders.
