Heh. If you replaced “leftist movements” with “human movements” then I’d be with you. Witness the ever developing criteria for identifying and excising “RINOs” from the Trump movement. Find any decently sized organization with humans in it, and you will find a subset of its members actively attempting to identify and excise inpure members. The fallacy you are demonstrating is the notion that such behavior is relegated to a particular other group, as though ostracizing behavior doesn’t predate the very concept of “left” vs “right”.
