critical theory is real and pragmatic yes.
but Critical race theory along with many other critical studies that had a brief flash of popularity in the 1980s such as critical legal studies – https://en.m.wikipedia.org/wiki/Critical_legal_studies – Became historical footnotes by the 90s/00s/10s
some of them continued with vigor — aspects of critical studies in feminism certainly blossomed in the 90s – but others practically vanished – yet not entirely gone.
The crux of my argument here is:
Fox News has dictated reality and created “critical race theory” as a threat.
but before July 2020, and you can search Google by dates which is how I confirmed it : it had no functional existence that could be a construed as threat
