I would never reduce the population through bloodshed or a limit on freedoms. That's not morally right, even if it is morally right in a grand sense. But I don't think one would need to.

I don't know that any work has "value", be it movie reviews or political commentary. That's a really tough thing to be sure about. Values seem so subjective.

I don't think attachment to one's species is any more moral than attachment to one's race or gender, but I'm not a believer in speciesism like Peter Singer, so I'm not going to go down that route.
