In my opinion there are two sorts of “sectarianism” in Scotland; there’s the obvious stuff like last night, or the city centre fights between the neds. That’s not really sectarianism, that’s just an outlet for the extremely poor, unhealthy, and forgotten lowest-class population of West/Central Scotland to take out their agression, frustration and stupidity on.
To me, of more concern is the just-under-the-surface vein that still runs through a large proportion of the community. Like someone above said, I have intelligent, level-headed friends who are extremely biggoted on this issue, and can’t seem to move beyond it. Similarly I have witnessed completely inappropriate comments at work about the recruitment/redundancy/management of colleagues as a result of them being “Tims”. This is passed off at un-PC humour when challenged, but with a minority the undercurrent is always there.
Regarding Lennon; he rubs people up the wrong way with his aggressive and confrontational attitude. I’m not sure retiring five years early from playing for his national side, GBH, bullets-in-the-post, parcel bombs, death threats, or 24hour security and panic buttons in his home where he lives with his children are reasonable sanctions for this.
