Kudos to you. Why would you seek others’ opinions when you are so sure of your own?
I don’t find “grab any opinion that confirms my bias and post it and then argue about the source’s credibility” to be a very good or interesting style of debate. Obviously it would not be difficult to find those sorts of sources that agree with me, but I don’t find “see, x agrees with me and I bet they know a little more about football than Tempo34!” to be a compelling argument in the least.
You act like you “seek out other opinions other than your own” as a means to do something other than confirm your preconception but I think we can all see that isn’t the case.
