The most paranoid fans in the world are without doubt celtic fans. No set of fans come close.
I'd say both of the old firm teams equally. Both think the refs are out to get them.
Aberdeen fans are right paranoid to be honest. They laughably talk about 'Glasgow bias' in refereeing and the media, as if you get refs and journos who support both the old firm, lol.
I think Aberdeen fans are very good but your right we think the refs are bias but I think that's normal with just about every clubs fans.
