I don't understand your reply. I didn't say that people growing up in different times would act the same or that people with identical genes would act the same. I'm arguing that different people will act differently in the same circumstances. If you want to establish that OP is absolutely correct, you need to show that people with different inclinations and abilities act the same way as each other when in identical circumstances. This seems self-evidently incorrect to me. People have varying amounts and types of mental faculties and so make different choices, even when presented with the same situations.
