i do not understand your logic you state possible status of rangers is of no relevance are you being serious the relevance is that the term 'old firm' was coined unofficially as a terminology to describe rangers fc and celtic fc now rangers fc are no longer in existence and you ask what's the relevance you also say it wikipedia is an encyclopaedia not a football fan site which i totally agree with the whole of this page appears to be written by fans of rangers fc it talks of sectarianism yet doesn't mention rangers fc had a sectarian policy but it mentions celtic fans marching on 'unofficial' protests and is the term 'old firm' not relevant to football fans because it is does not have any cites anywhere printing that there is no 'old firm' for the record who has the right to say whether the term is relevant or not
