If you do not support progressive ideals, you do not belong in the Democratic party.
You apparently believe the Democratic party should also welcome Republicans. I don't. I'm sorry you feel that makes me an extremist.
If you want to oppose financial regulation, universal healthcare, a living wage, etc., by all means, join the Republican party, because that's where you belong.
It is my way or the highway when it comes to ensuring 27 million Americans who weren't covered under the ACA, it is my way or the highway when it comes to getting money out of politics and overturning Citizens United. It is my way or the highway when it comes to accepting corporate or PAC money to fund political campaigns. If you don't like that, can't accept that or can't understand why, you're not as smart as I thought you were.
