So let me elaborate a little. Is British Society a bit more polite than many others because of the colder climes (hey, that works for Canada too)? Do societies in warmer climes with more resources have the freedom to be more open, generally?
Does the fight for resources bring out the worst in cultures, fostering discrimination?
Would a new world where every birth counts to raise the population work against the expression of homosexuality?
And how can we use these forces to write some really good speculative fiction?
