Only those who were born and brought up in the Glasgow area is able to truly appreciate the insidiousness of this Rangers/Celtic, Celtic/Rangers divide.
As Jim Brannigan says, it has driven people from their homes, and even their countries.
Most of you will never know the fear of being approached when you are standing at a bus stop, by a gang of threatening looking characters, and being asked "Whit team dae ye support?"
If you want to avoid a kicking, you better give the right answer, otherwise that's you for a bruising.
This; for no other reason than the fact you may support another team, and let me tell you from painful experience, it doesn't help to say "I'm not interested in football"
While there are efforts on the go, to try and stamp out this prejudice, it is in a lot of cases a waste of time.
There is a red neck element on BOTH sides, who received their hatred mixed with their mother's milk, and they will always exist.
Those are the sort of people who look on their offspring marrying a member of the opposite faith, in the same light as a KKK member who's offspring married a black person.
Make no mistake about it, it's as serious as life its self in certain quarters, and as I said at the start. You have to have been there to know what you're talking about.
