"Shouting echo chamber" = a claim made when one side offers any criticism of the other; i.e., that any disagreement means you're in an ideological 'echo chamber.'

Why not talk to a real Democrat Socialist, ask what their platform goals are and pay attention open mindedly to the answer. You seem to be parroting "the party" and therefore could be being misled 

I hope being a progressive mean you have an open mind to different opinions on the direction our country should be going.
