@Lash,
I disagree with AOC, I think she goes too far on immigration in wanting to eliminate ICE. Yet, I don't think when she expresses her views, she pitches her views as a Progressive vs. Centrist battle in quite the same way as you do.
It is like your end of Progressives are in a battle against the democratic party itself in order to do it over in the manner you all agree with. It's not right; if you guys didn't agree with the Dem party as a whole, ya'll should have formed your own party. It'd be like a Baptist coming into a Church of Christ and wanting to change into a Baptist Church. All of them are Christians, yet there are distinct differences that are irreconcilable unless some series compromising on both sides are done.
