I agree with most of that but do think that Friend in particular has an agenda against SAFCThat's true, I don't think he has any agenda against us I just think he's one of the poorer referee's. I always think it's harsh when this type of incident is given as a penalty because they're not given consistently across the board.
I do think a referee can have a bias against certain teams without having an agenda against them, it's likely that most referee's have some sort of preconception about teams from the media and other outside influences.
I would highly doubt (and hope not) they would consciously act on these preconceptions but they could play a part at some level in their decision making.
