We need to abandon trying to defy the right's definition of us and stop chasing for their approval.
They will slander us no matter what, so how about giving them good reasons? I hate making it seem like history repeats itself, but under Reagon, Democrats would often deny being a “liberal” as the word has gotten such a bad connotation by right wing media. Seems familiar, especially when the guy today also uses “Make America Great Again” as his slogan.
Stop playing defense, start making change. Stop constantly compromising on, for example, infrastructure bills hoping you'll appear moderate, only to be slandered as an extremist right after. Republicans will do everything in their power to stop such a bill from passing through senate, whilst then promoting it as one of “their” achievements, as governor or for their constituency, when receiving the funds they fought against. It's ridiculous, it's not playing fair, it's contradictory.
That's reality, and the strategy the Dems have been following since Reagon is working only in a fantasy world far removed from ours.
