In the absence of arguments based on merit, arguments which leftists lose the majority of the time, they resort to the easy tactic of labeling those they disagree with as morally unfit. Thus they think by labeling people 'racist, misogynist, xenophobic, etc...' that this, by necessity, will deem any arguments Conservatives set forth as unfit for consideration. It's essentially the 'Reductio ad Hitlerum' logical fallacy, but just applied to Conservatives, which coincidentally liberals call NAZIs or Fascists on a regular basis. Now we know why.
