It's because actions speak louder than words, you dolt.

Your actions are "only ever criticize the actual left" and so you are regarded as insincere because WERE ON THE SAME SIDE. But instead you NEED to be morally superior and make sure everyone knows it. It's the same as the people who didn't vote for Harris and their constant whinging about how the Dems never listen and theirs was the only MORAL vote. I think that shit was dumb, too, but at least they have principles.

If you just look at your actions, it appears you want to delegitimize the left in favor of the "centrist" dems as though moving right is a viable strategy that has worked for the Dems in the past. Basically, we see a clown.
