I was in the UK training with their Para Regiment...an exchange program and they had a lot of experience from their days in Belfast vs the IRA. On a weekend, some of the guys wanted to take me to a "proper" football game so we took the train up to Glasgow, got a few hotel rooms and enjoyed a Rangers weekend. I became hooked because Rangers had USA MNT players on their team regularly (Reyna, Bocanegra, Edu, Beasely) and being an Army Ranger, the club just fit. So I followed the club, watched all their games and would attend a game or two. When I started to attend more regularly, I started to notice the huge sectarian angle ...huge. That angle not only was in Scotland but in Belfast/Northern Ireland. Protestants vs Catholics...and I was a Catholic supporting the Protestant club. But it was also hugely political with Rangers supporting the Queen and the UK while Celtic supported Northern Ireland joining the Republic of Ireland and Scotland independence from the UK. Its crazy and something that I never would have imagined in a 1st world country...
