I think you're mixing democracy with freedom. You are free to vote or not, but in a democracy there are consequences to your choices. In America we have taken our democracy for granted and stand out, again, among democratic nations for our abysmal record of voting as an electorate. Others are setting standards as a reminder of the importance of voting. Australia and Singapore are examples.
Is a democracy not the "freedom" to make a choice? I've seen dictators make voting compulsory and end up w/a 98% result for the despot. I mean, if you want to be pedantic that's still "rule" by the "people" (under gun point).
