I had a conversation with my wife about this. For context, I mostly agree with you, however this is something you and a spouse should agree on and have a plan for. We have two young girls, so there’s that. Additional context: my wife is Jewish by birth.

Her reaction was immediate and unequivocal: we are going to do everything we possibly can to survive.

I guess generations of natural selection on a genetically isolated population really -does- matter!
