I Often Have A Differing Opinion From The Majority
The second you decide that this issue, this opposing person or group, is so important/bad/whatever that it's okay to drop human decency and act like a scumbag in order to fight for/against it, you lose something in yourself that's more important than words can describe. Something that you can't get back until you recognize what you've become, how far you've veered off course, and choose to bring yourself back.
Look at the issues that are closest to your heart. Now look at the worst ways that you treat the people on the other side of that issue, when you're arguing with them and trying to win the argument, in the name of fighting for what you think is right. Look at the person you are in those moments, when you're treating people the worst that you ever treat anyone. Is that the person you want to be, when you're fighting for the things that are most important to you? Is that how you want to represent the issues that mean the most to you? Can you look that part of yourself in the eye and be proud?
