Casting votes before swine

Little known fact about Me:
I once went very much out of my way to cast a vote in a local election I had no intention of participating in, and NO interest whatsoever in the candidates nor the outcome.  I did it because someone whom I've known, loved, and respected my entire life told me she was going to vote, and was calling other white people to tell them to be sure to vote, too, because a black candidate was running against the incumbent, a white man who had held this office for decades without any significant challengers.
I was SO shocked that, even minutes later, I couldn't remember exactly what my reply was, but I know that I did manage to verbalize (poorly, I'm sure) my profound opposition to this blatantly racist and unreasonable attitude.
And that's how I came to "get out the vote" for a man whose name and face I cannot remember, in an election I had NO interest in, that he had not a chance of winning in the first place.  I had the power to cancel out just ONE single vote that I knew was being cast out of ignorance, bigotry, hate, and/or fear, and I felt obligated to do so.
P.S.  The incumbent won anyway, as everybody knew he would.  Did I make a difference?  In that election, absolutely not!   In my own heart?  Absolutely.  I was the tree that fell in the forest.  And I HEARD mySELF, even if no one else did.
