I'm rather good at seeing both sides of an argument, however that has its negatives when I know that the other side is painfully weak against the correct side. I get passionately defensive when somebody challenges something that I know to be 100% correct.
Back on to the question, I think it's just because I've tried for so many years to become this neutral, fair person, and that is born out of a pretty disruptive childhood. While I've never been a tear away, I wasn't exactly a star child, and before I settled down with my fiancee I was terrible for getting into pointless fights. I followed by example of the people I wanted to be my friends, and always knew that I wasn't a terrible person.
Now to try and make up for a couple of years of pretty negative behaviour, I have spent most of my life striving to help others, stop bullying and promote equality in all areas of life. I have long sinced made up for past mistakes, but I still look back and feel ridiculous for changing who I was. This is what I believe makes me a peacemaker. Sort of like a can you know happiness if you've never felt sadness thing, I suppose.
