That doesn't change the fact that the "Center" in America is pretty insanely far to the right.

Of course it doesn't.

Now what do you suppose has a better chance of getting what you want?

1. Telling the center to get fucked because they're not radical communists like yourself, or
2. Compromising with the center to prevent the insane right from taking over the core of this country's government?

Well. We see how well option #1 worked out. Enjoy the chaos. Keep holding purity tests and pogroms at your peril.

One day you might grow up and realise that adults compromise with each other to better the country, and don't stamp their feet and scream "BUT DAAAAADDDDYYYYY, SHE ONLY AGREES WITH 99.9999% OF WHAT I AGREE WITH AND THAT 0.0001% THAT I DISAGREE WITH IS LITERALLY THE MOST EVIL EVIL EVIL EVIL EVIL I HAVE EVER SEEN ON THE PLANET WAHHHHHHH!!!!!" whenever they are faced with any opposition, whatsoever.

TL;DR: Enjoy your Trump. You helped make this happen. Grow the fuck up, or see it get even worse.
