ofc, only other people have bias, never you
Am I biased when I say that the Fulham crowd was mostly lethargic, even when goals were scored against a top team? It's what everyone who paid attention saw!
Heck, they had a penalty to go ahead in the score again and 99% of the fans behind the goal had their phones out to take a fucking video...
If anything, having a preference here, which you obviously do, means that you overlook these things just because this is convenient for you. Some people stick with the PL due to peer pressure or whatever, since that's what their friends watch and they don't want to be left out. Maybe that's you. It ain't me. That doesn't make me biased, it just makes me disagreeable.
