The anthisis of the made up word Zeeper is Zelocon.
As in she is a neo isolationist Zelocon on steroids
Sorry, that won't work. Try something else.
Also another logical fallacy - ad hominem. And another - false dichotomy - e.g. if you are not a Zeeper you are a Zelocon which is defined only by not being a Zeeper, but it is something really really bad, I am sure.
