This post, as I clearly said in the OP, is about those who think the only way to get progress is to hate the DNC and the grassroots it has built.
I don't believe you that these people "hate the DNC and the grassroots it has built".
People hate the corruption and lack of transparency within it. They want to change it. They want to fix it. That's why they run with the Democrat party. It is their party. They want it fixed. I don't understand why you have such a problem with that and demand they run third party. All that would accomplish is delaying progressive policy changes, so long as the first past the post and other 2 party system mechanics are in place.
