To push the limits of the self ID ideology and see if there was still support for what was being taught to students.

People are pushing back in Canada. Just like the male weighlifting coach. When a transwoman started to set weighlifting records for Canadian women, the coach self ID'd as a woman, entered a competition and went and blew a couple records way out of the reach of transwoman. Basically, if a biological woman can't hold the record, then neither will a transwoman.
