You don't know your history very well. People have been forced at gunpoint to defend the democracy that we wanted them to have. Not the one they, themselves, voted in. Examples of this can be pulled from Korea, Vietnam, the middle East, South America...
Generalities like the one you made there bite you in the ass--in this case twice as you're wrong on both count. Communism didn't force anyone to do anything--a dictator did. And, as said, people are as likely to be forced to die for democracy as they are for anything else, so democracy can't take the moral high ground.
And, just to add to the mistakes you've made in that statement, you'r confusing Communism, an economic system, with a system of governing (everyone gets a vote). A communist country can also be democracy. Just as capitalism--which we have forced people to defend at gunpoint--can be fascist. The economic system of a country doesn't decide whether it will be a democracy. Nor does the system by which the country chooses leaders decide its economic system.
Would you care to play another round of ill-researched political generalities or would you like to take your foot out of your mouth first?
