Had a job that put me into a socialist country for a couple years - very quickly cured me of any left leaning tendencies.

In my next job, I had liberals calling me a liar when I shared my experiences. I would say "I don't care what you believe, I'm only telling you what happened to me, and the people I lived with". Some people thought visiting a country made them experts on it, and you couldn't possibly learn more by actually living there.
