I'm very glad that people vote. I prefer democracy to the alternatives, and if nobody went out and voted, there would be no democracy. I understand why there's a push on to get people to the polls, especially for people who want to get others to vote for their candidate of choice.
That said, let's look at some of the standard reasons people use to try and convince an individual non-voter, such as myself, that they should vote:
It will affect the outcome of the election.
I don't see how, especially given the Electoral College. There have been four presidential elections (prior to this one) since I turned 18, and I'm convinced that if I went back in time and voted in any of them (for either candidate), the results would be exactly the same. Once, someone asked me if I had voted in the 2000 election, and when I said I hadn't, they blamed me for the George W. Bush presidency. But Gore carried California without me. The only possible way I might have affected the outcome is if I had lived in Florida...and then, my vote might not have been counted. More recently, someone on Facebook claimed that every non-voter "may as well be voting for Trump." Because some reason, they think non-voters are specifically not voting for their candidate of choice.
Soldiers died for your right to vote. If you don't exercise it, you're disrespecting them.
I'm glad I have a right to vote, if I should ever choose to do so. But a right to do something also implies a right not to. Soldiers also died for my right to bear arms - my choosing not to own a gun doesn't disrespect them. Soldiers died for my freedom of religion, which also includes my right to choose "none of the above," which I do. The only thing that would be disrespectful would be giving up my right to choose. If voting ever became compulsory, it should be known as the "duty to vote." And "they died for your duty" doesn't have the same ring to it.
If you don't vote, you have no right to complain.
I'm generally not interested enough in politics to have complaints on that topic, but I don't understand the reasoning behind this either. If anything, it should be, "if you vote, and you get the results you wanted, you have no right to complain." But even then, I would understand if people still complained, because they have limited options and they may still have complaints about the candidate they voted for.
