They already did that in response to the left-wing loons which is why the whole world is swinging right. I agree with you and wish they now did it too with the right-wing loons and finally realized both left and right are evil and will develop new philosophies born out of reason, compassion, and objective evaluation of the impact of our actions... but sadly I only expect things to get worse so long as both sides remain vile and toxic groups.
My sincere hope is that people around the world see the madness in the US and say "Whoa, we don't want that sh!t here..." and vote against the right-wing loons.
