John money coined the phrase is gender role and sexual orientation. sources claim that he is not associated with the term gender identity, but the same sources do not name who did coin the term and do say the term came about in the 1960s, the period while money was doing his """"research"""". https://en.m.wikipedia.org/wiki/John_Money

this research involved The grooming of David Reimer into thinking he was a girl, which ultimately failed because Reimer had a brain. nonetheless, money use this abuse to insist it was proof of gender identity. this declaration was made around the same time that, according to Reimer, he and his brother were made to do sexually suggestive things to each other by Money. https://en.m.wikipedia.org/wiki/David_Reimer

of course the pedophile mods at Wikipedia will never let the sexual abuse allegations see the light of day on their website. https://www.psychophilics.com/post/dangerous-dogmas-the-tragedy-of-david-reimer
