That IS badly thought-out - the whole POINT of the Amazons is that they're a nation of women, and always have been. I mean, for thousands of years it's been only women on that island, and now they're adding in men? If nothing else, how are you supposed to keep the population stable if you add in the potential for baby-making? Everyone's immortal on that little island; there are no deaths except through battle or accident - you'd have the whole place crawling with people within a few generations. Then they'd have to immigrate, and then you'd have lost the whole point of Themyscira being a haven, a paradise, a last refuge for the romantic Greek ideal. It's a damn stupid idea, is what I think.
