As a concept, I feel like Genosha's fascinating. Of course different countries would respond differently to "the mutant question," and some of them might even be defined by it. But you need a solid interest in economics, politics, demographics, culture, and all the other things that make up a nation to follow that up, and that is something Marvel writers have rarely taken time to do.

Plus, that "metaphor of the moment" problem has always been a little bit of the problem with the X-Men (they are every marginalized group in humanity and none of them, all at once), so it's not too surprising Genosha would end up echoing it.
