Killing surplus babies is a “leftist” position? When the Nazis killed Jewish babies, we thought they were “right” wing. And both the left and right include anti-Semites (one can argue that Jewish survival is to make sure that neither extreme comes to power).
We should remember that “left” and “right” refer to which side of the parliament different groups sat on in the French parliament during the French Revolution – and that Jews didn’t get the right to vote or hold office in France until after the revolution.
We also need to remember that in basic economic matters, most frum Jews tend towards the “left”, and indeed, our community has a history of left-wing positions in many areas such as providing education for all and supporting the poor and regarding such support as a duty.
