im not going to go into his Twitter account and look for it. he likened trans people to Rachel dolezal (or whatever the fuck her name was) and said people would be criticized for denying that trans people are what they identify as. "discuss" he said.
when people rightfully shit on him for implying that trans people are frauds like her, he weaseled out like every coward Schrodinger's bigot saying "i said 'discuss' academically" or some stupid shit as if that undoes his equation in the tweet.
he also said in another tweet that being trans is a choice with something like "some men choose to identify as women" and vice versa. he's stuck on chromosomes defining gender, which is unscientific.
then he wrote a column or some shit about it with chromosomes defining women, which is unscientific, and on his podcast he platformed a transphobe, didn't challenge her and even agreed with her.
like all transphobes he's lost the plot and has completely rejected the science on it.
