Tl;dr: Justice Democrats interference has cost Democratic Party approximately 7 seats in 2018; even after the election, instead of showing any signs of remorse, they are acting as if this was exactly the outcome they were going for; Justice Democrats criticism of Pelosi hinges on double standards, impossible standards, and victim blaming; using the possibility that holding back on impeachment might cost Democrats progressive votes to launch attacks that do cost Democrats progressive votes is a self-defeating self-fulfilling prophecy.
I am all for supporting and encouraging more progressive candidates, but holding the entire country hostage with “I will vote for Trump out of spite if my favorite candidate doesn’t win the primary” is not how you do that, it’s how you help fascists win. Please stop worrying about scaring away the moderates, and worry more about amplifying rhetorics that discourage progressives from voting.
