(Another) Question for Old Firm fans...?

Obviously nobody knows the exact figures but in your opinion, roughly what percentage of true Rangers fans follow England or N Ireland ahead of Scotland? and same for Celtic fans and Rep of Ireland?. To me, its all pretty sad and a bit pathetic, all this 'Rule Britainnia' tripe from the blue side and.. I remember a Scotland, Ireland friendly game few years back when Hampden had about 15-20thousand 'Ireland 'fans whom it appeared were only there to boo the rangers players in the Scotland team. Surely its time for Old Firm fans to get right behind Scotland (which is made up of many of your own players by the way) This doesn't mean you can't still follow your other nations which your songs and history say you 'have' to do! zzzzzzzzzzz
