References to purity when discussing voting (as in, "leftists need to stop their purity seeking and vote Biden") just read as genocide denial and apologia to me at this point. Perhaps you think that it is strategically necessary to hold your nose and vote for Biden. But saying that people who don't agree with you on the strategic necessity of voting for a genocide enabler are seeking purity is such an obvious distortion of reality that a person might start to wonder if you actually *are* holding your nose. Maybe he smells just fine to you.
People are complicated, but I don't think a person can understand and feel even a portion of the impact of Biden's continued material support for Israel and say that people who won't vote for him are seeking purity. *Purity.* The word choice itself is cruel. In my opinion, personally.
