Some additional non-spoiler lore that people might not know about the guy:

While he had his practice in the US, he actually immigrated from New Zealand to the US to do the research that he wanted to do, as it was impossible to do so in New Zealand at the time as New Zealand was a conservative but quasi communist country and both main political parties reflected this (one was leftwing populist and the other was Christian socialist). We are talking about a country where the TV and radio is 100% controled by the government and where newspapers are the only non government owned media (but who are somewhat reliant on government advertisements).

Helen Clark (Permanent whinger, outspoken one world government globalist, former New Zealand prime minister, former head of the UN Development Programme, wantabe UN general secretary and current chairperson of UN Covid-19 investigation) was good friends with him when he was alive. She opened an art gallery in the town of Gore (New Zealand's New Zealand) in his name.

He was also closely connected with other politicians and supporters of the bloodless revolution in New Zealand in 1984 (government swapped the economic system from quasi-socialism to extremist neoliberalism overnight without regard for human cost). These people used social liberal reforms as a means of distracting the public from how they were selling off the very considerable amount of state assets to multinational corporations on the cheap so long as they got a considerable kickback.

Now that I have bored people half to death, his wacky idea of 'treating society' rather than the person looks sane compared to his idea of "fighting Fire with Fire" in stopping **** shit with gay **** shit. Which is why videos like this one are made and will probably increasingly become the norm.
