Her and Bernie have been insufficiently pro Palestine. To the degree of negligible support of the genocide. To the point of distancing themselves from Ilhan Omar. I think they rightfully know they made a mistake in an attempt to be strategic though. Which they are backtracking on now.
The reason these organizations (DSA/PSL) exist is to move politics to the left. If you criticize them for every attempt to do so. You are literally just contributing to the Ratchet Effect of US politics. That type of milk toast politics from "the left" in the democratic party did not prevent us from getting to where we are today.
The Democrats did everything to do exactly what you are advocating for and surprise surprise we are here in full out fascism today. Maybe try to listen to those a bit to the left of you. We literally warned that this centrist politics would end this way.
But somehow we're being blamed for it. Even though at every turn the Democrats prevented Palestinian voices and ran on "building the wall".
