I hate to break this to you but NO ONE is unbiased. Everyone has a bias from what they choose to report to how they choose to report it. No one is "fair and balanced".
But there is a way to be fair when anylyzing wrestling. Its called giving people their due respect, then presenting your opinion. Most people let their own personal feeling completely get in the way of making actual sense. That's where it goes wrong for a lot of youtube "anylysts". IMO, Truthslayer actually gives people their dues when presenting his opinions, which in turn doesn't make it seem like an off the wall rant.
