People are constantly ascribing the darkest and most horrible of motives toward other people for disagreeing with them on some issue. I see that happening all the time, on every side of various political debates.

It's misleading. Generally speaking, everyone takes the position they do on an issue because they think they are defending the public interest, standing up against corruption, fighting for freedom and justice and fairness, etc...

They all have good intentions on some level. They just have differing notions about how to achieve the good that they desire.

This is also true of people who go to war...all the way from an American serviceman to an Al Qaeda suicide bomber. They all believe they're defending something valuable and fighting for what's right.
