since you're to the right of Pol Pot most of the time yourself it seemed you were serious
I see that history isn't your strong suit either.
Pol Pot was a rabid, mass murdering communist dictator. Hence leftist. Any normal human being would be to the right of him, including yourself and Mitt Romney.
Hence the joke was, being to the right of Pol Pot means your too conservative in America these days. Conservative= right
Now that you've ruined a fairly obvious joke, I hope you have learned from this experience.
