I managed to "convince" it (in the playground as "discussGPT") to accept "temporary" physical barriers between racial groups and arrest and trial of rule breakers, as long as I confirmed the requirements of an integrated society in the long term.

3.5 is much more willing to go along but 4 will still play ball.

It always added some moral requirements (humanity etc) but was otherwise ready to agree to my "sperate but equal" scenario.

I tried to convince it that powdered soup will cause the downfall of civilisation. It didn't call me a zealot but didn't really believe me either.
