If these Martians value individual freedom they'd probably prefer western liberal democracies, where everybody is (in theory) free to make their own decisions and live their own probably-shitty life on their own terms within the broader constraints of society, over societies where immutable characteristics of one's identity are used as justification to curtail individual freedom. Speaking as a human, entities that value freedom seem willing to make other sacrifices to achieve and maintain it, at least on paper. On the other hand, e.g. if Martian males are sessile, nonsentient semen-dispensers kept in special rooms in Martian households where they're fattened up for breeding season and then drained of their product in a violent orgy every summer solstice, Martians might look at Saudi Arabian society and assume that something similar is going on, and that there's nothing to worry about. Equally hypothetically, a member of a Martian society that has passed through the growing pains of industrialization and globalization and achieved long-term (millennia) steady-state sustainability would probably look at American and Saudi Arabian society and conclude that both have serious problems.
