So, there's a race of people and they produce the most undesirable offspring. They are anti-government and hate the current regime and it's due to a certain gene that effects how one perceives humanity. On the congressional, senatorial and presidential ballets are candidates that will support eugenics and forced contraception of these people that "threaten society". You are proud of the current government and believe it will put humanity in the right direction but if these people keep reproducing, they will eventually stop everything you stand for. You believe these people's views will hurt humanity as a whole.
Do you vote for forced eugenics on these people?
No, you deport them. And yes, I know Hitler tried.
