Not bias, Schteff.
Some of the examples you gave were mistakes by the ref, others showed lack of character. Like players, some refs bottle difficult decisions, especially ones that will probably determine the outcome of a game.
Kompany should have been sent off. He lost his appeal. Whether or not the tackle would have gone unpunished without Rooney's intervention is immaterial. The correct decision was made. No favouritism. The travesty would have been for an incorrect decision to have been made and the ref called to task for failing to act.
Refs are human . Most do well to get as many decisions as they do correct. It's bad enough that people expect them to have superhuman perception. They don't need to be accused of being partisan as well, because it's not true.
They're not mistakes, I deliberately chose decisions that can not be construed as mistakes. The ref cannot change his mind because a player complains so Rooney's reaction is not immaterial and shows bias. It's not a mistake when a ref ignores the rules it's bias, unless you're going to suggest he pulled out the wrong card or forgot the rules.
