This is a very US perspective I think. Here in Germany there are many that think communism is fairer than capitalism (although perhaps unrealistic to attain). Insulting something/someone by saying something is communist or someone is a commy is not really something that happens here (except perhaps in politics).
[Edit] Just to add some perspective:
Communist parties in european parliament

Even large european countries have communist parties, some even voted into office (such as france, spain) and in the case of Spain even in the ruling coalition.
Implying this is a western view neglects to realize how much US vs. Soviet propaganda has shaped the US population.
