Is America the most polarized country on this planet ?

Your governments have always been either right wing republican or left wing democrats [ never a center party ], people seem to be either God-fearin', apple-pie bakin', flag-wavin', "Lets ban , weed, alcohol, tobacco, etc. ". Or , conversely, pot-smokin', beer-drinkin', -lovin', " Wup dude? ". Are all Americans either Christian Conservatives or Easy-going Liberals ??
