Didn't Vote? Then Don't Talk

You care enough to criticize or be a naysayer about the election, then you would've cared to vote. On the other hand, there are those who were so passionate in their support for a candidate, and that's wonderful, until I find out they didn't vote. I understand there are certain things that would hinder someone from registering (age, citizenship, disability), but otherwise, voting is a national privilege. Our ancestors fought and died for this right. Voting is the ultimate voice. I thought everybody knew that. So what was all the talk for? I just don't get it.
