I do think that for all the stick Rangers and Celtic fans receive for their bigoted views, Rangers as a football club deserve a degree of blame.
Every club has their knucklehead element, some more than others.
But when a club maintains a policy of exclusion for so long as Rangers did it gives the bigots on the terraces and in the stands credibility.
Dave is quite right in so far as the Catholic population isn't so high (I'd have thought it was higher than 15% but hey ho) in Scotland so as to justify a large percentage of Gers players coming from that background. And you could never advocate quotas or the like.
But I find it odd, particularly post 80's that there hasn't been more players of a Scots/ Irish Catholic background making the grade there. Are they seriously arguing that none were ever good enough?
I could understand Rangers as a club or even said players being wary of such a move on the backdrop of a troubled period as was the late 60's-80's or at various other times prior to that.
But since then, against a backdrop of peace an reconciliation in NI, when player movement has never been so easy and when cash is king it's a rather odd anomaly. A sad relic from a bygone era. Which is pretty much the Old Firm in a nutshell.
