If I wanted to be cruel, I would say that they started denying evolution and Darwin. Now they are proving Darwin was right.

Sadly there are already fanatic terrorist who shoot or bomb planned parenthood clinics and attack women, immigrants and gay. It is the present, not the future. And it's been happening for a while now. For US to be great, it would need no solve its violence and white supremacism problem. And I really hope, US solve it and becomes great.
