I encourage you to watch the interview I posted. TL;DW the Dems should achieve their goals (which are better than those of the Reps) by playing like the Reps. Again, that’s the short version of the video which doesn’t do it justice, so if you want to argue it, I encourage you again to watch the video.
Completely agree with you on the definition of centrism. Many North Americans online seem to have a problem with things being gray, coming to a consensus, or that great ideas (and solutions) can come from anywhere. If you don’t agree to everything a group says “you’re against them”. It’s primate thinking.
