Lefty is appropriately taken as a derogatory epithet since lefties throughout history and around the world have proven to be such complete embarrassements for all humanity with their childlike perception of human nature and history. Politics is a serious business with much at stake and conservatives (the "righties") approach it with the proper mindset, sensible to their limitations and moderating their pursuits for the greater good, nothing embarrassing or infantile in their perspective. If you want a derogatorty term for conservatives, use Chomsky's "plutocracy" (when they are wealthy) or call them brainwashed, duped, manipulated, short-sighted or whatever you think their particular flaw may be. That's the beauty of the "lefty" slur, it covers all the morons holding the idiotic perspective we all need to just talk to each other, generously care and share more. To achieve an similar effect with conservatives you end up applying a term that is apt for only for wealthy elites, international investors, perhaps religious fundamentalists or racial supremacists.
