Are we a democracy? or a republic?

I AM ADDING THIS TO THE FRONT AFTER THE FACT...YOU KNOW THAT probably the single biggest group of proponents of a democracy are communists correct? I say again this is not debatable, its proven fact. Interesting huh now go learn & research & think???
I will keep this diatribe short but just to reaffirm what I went off on a few days ago....PAY ATTENTION to what your kids learn in school, IF you think they aren't being glazed over in BS you are wrong...don't blame it all on the dam PS3 & the WII. In no more years than we are talking about it we have honest to god die hard Conservative Republicans that bleed what i bleed, AND HAVE BEEN ELECTED TO PUBLIC OFFICE, that would literally stare at me clueless with the question i posed earlier....You have to pick one - Are we a democracy or a republic?
AND I SAY AGAIN for anyone that reads it or wants to argue there is NO argument on the question just one more representation of what happens when one group gets total hold of all the things that a society winds up turning to for both its entertainment & education (and most other things too).... They have Hollywood, DC at various times of course, and most importantly to aid the indoctrination, the damn NEA & College professors and all things learning....pathetic.
