Could 'climate delayer' become the political epithet of our times?

Already we argue over whether to call them climate deniers, skeptics or doubters. Alexandria Ocasio-Cortez might have hit on a more devastating attack

It's a fantastic time for verbal abuse in American politics. Donald Trump loves a schoolyard nickname, insulting everyone from "Crazy Bernie" Sanders to "Little Marco" Rubio. In turn, the president's opponents, and sometimes his allies, have called him a moron, a motherfucker and mocked his tiny hands.

But is there a way of using name-calling, not just to insult, but to introduce a new political idea. It seemed like Alexandria Ocasio-Cortez was doing that this week when she used the term "climate delayer" to call out those dragging their feet on climate change.
