I feel that a lot of the criticism of Archer in this episode is based on naivity. I mean, why don't we make Saudi Arabia give women equal rights? The exact same reason Archer doesn't want to interfere with Vissian culture: it will create a diplomatic shit storm, quite possibly lead to worse oppression, and also possibly to armed conflict. In the real world, diplomacy is about keeping a dialog going. Forcibly going against another country's laws and culture can create hostility or even shut the dialog down completely, so should always be regarded as an extreme and last solution.
