In politics, you'll often see parties taking the opposite sides not to stand for what they believe in but rather just to not be on the same side as their opponent. They are taking sides for the sake of taking sides. I'm all for doing things differently and going against the status quo as long as that's what you truly believe in. However, just because you don't agree with someone doesn't mean they are your opponents. There can be more than 2 sides in a fight.
Maybe we are heavily influenced by sports where it's always between 2 opposing teams or by the media that tend to over-generalize the demographics, we tend to believe that if you are not on the winning side then you are on the losing side.
I think that it's important to be able to take sides and make a stand for your ideology, principle or argument. Just remember that there can be more than 2 sides and the other sides aren't always your enemy.
