I don't think so; at least I haven't had this thought and haven't heard it used in insults for the movement.

I've tended to assume that neo<foo> is disreputable in a larger sense, because it indicates a departure from older, popular principles. Modern neoliberalism in particular suffers from an association with neoconservatism, with progressives damning it as a vaguely social-left reinvention of Fukayama. Both have acquired a connotation of elitism, aggressive monetarism, and foreign intervention that sours populist movements from either side against them.
