Meh. I have tried it. And I have mostly just found that other people's opinions are wrong.I am an MLS fan but I can understand the difference between the two leagues. There's a such thing as middle ground.
I also believe that my opinion on somebody or something can be swayed over time so I don't pick a fanatical one sided argument and defend it to the death. I allow for other people's opinions and facts to change my views. It's a pretty cool concept.
