If some conservatives absolutely insist on lowering their own population, who am I to stop them? Actually, the louder I beg them to stop and follow the science, the more aggressively they seem to be killing themselves...
Killing people off in conservative areas just further entrenches conservatism there. It's a lot easier to get 10,000 people to do what you want than it is to get 100,000.
And even if Wyoming or South Dakota only have a few thousand people they still get a representative, two senators, and three electoral college votes.
