I'm not claiming to be an expert about the Old Firm by any means, but I don't know of any other rivalries with such a strong sectarian element to them. Add to it that both teams are regularly 1-2 in the SPL, play each other many times a season, and it seems only natural that it would be among the fiercest rivalries in sport.
I moved from Glasgow, Scotland to Boston, US. I have really got into the Red Sox thing, the Red Sox/Yankees rivalry is nothing compared to rangers/celtic, which is no bad thing! There are other worlwide soccer rivalries probably even more bitter than Rangers v Celtic.
