Presidential election years are always contentious as the leadership of our rich, powerful country is at stake, but this year, it seems there is more intolerance for political discourse than we've ever seen before. In reality, that's probably not true; intolerance for people's thoughts and beliefs has, sadly, always been a part of what makes human beings human beings. Our intolerance has caused wars and widespread human misery, leading to the deaths of hundreds of millions of people, mostly innocent, over the centuries.
