Issues in the 'Justice' vs. 'Corporate' Dem Fight

The Dem primaries are starting and I'm getting 3 or 4 emails a day explaining why we must elect Commies (Justice Dems) over the Moderates (Corporate Dems). The issues are very clear between the two.
They both support huge tax increases on the rich and increasing environmental restrictions to save the planet. But the big 3 reasons we must vote commie are:
1. Free college tuition for all students.
2. Free medical care.
3. Stop Israel's genocide of Palestinians.

The first 2 are obvious pitches about money. But I don't get No. 3. How many people are saying: 'I'm voting for the candidate that helps the Palestinians the most!'
