They don't live in seclusion to one another because the women said so, they live in seclusion because it is the will of the forest - and by all accounts, the men seem to devote more of themselves to serving such a cause than the women who live in luxury by comparison to the isolation of the men.

I think it's dumb that there's such a vast difference in height between Xaela/Raen men and women though as far as I'm concerned two wrongs don't make a right and I've rather not see Viera subjected to the opposite scenario.
