It’s exactly the same way that “alt-right” became popular around 2015 originally to self identify as a life long liberal who felt they could no longer support the political left, but also weren’t comfortable with fully supporting the political right. It was seized upon and redefined to remove those people’s ability to succinctly identify their unique position, to maintain the artificial 50/50 left/right divide in the public’s mind.

And yes I am aware that it was once used by some shithead nobody cares about before that, but I’m talking about it’s popular use in recent times.
