As the party fielded more and more candidates who championed economic-right policies in order to attract corporate donations, the idea of “purity testing” was turned into a stock phrase to attack critics using labels, instead of justifying it on its own terms.
Phrases like “moral purity” now serve two functions: firstly, to dismiss criticisms from the Left wholesale without having to discuss them directly, and secondly, to blame them for the rise of fascism.
In theory it was also supposed to serve a third function of bullying the Left into voting Democrat, but that didn’t work.
How about you shut up. I get that the progressives you’ve always hated keep getting in the way of your enthusiastic capitulation to everything the right wants you to do, but no one’s buying that you’re on anyone’s side but netanyahu’s anymore.
Good luck with mid terms!
Have fun blaming everyone to your left because your party won’t listen.
