Still doesn't answer my question why the majority don't stop the minority acting like the idiots we both agree that they are?
They do, by and large, but you have to understand the dynamics for this to happen. Bear in mind it's all seated and you'd need the perp(s) sat in near proximity to you in order to stop it. You can't wade in with fists, that's stupid so how do you propose stopping, what I'm pleased you accept, are a minority?
How I've seen it happen occurs amongst groups of lads who've all come down to an away on a coach (It's been almost totally eradicated at my home team's ground due to everyone having sat near to/next to the same people for years - decades in my case) and because boozing is not allowed on the coaches, the urchins are using Ching or speed as their 'pharma du jour'. This gets them rowdy and as they congregate together, they get some group bravado and the first daft comments sound. If these aren't challenged, they get bolder and the comments get louder. They soon become known as 'Commodores' as in 'once, twice, three times a season' and then, they don't come anymore. But they will be replaced by another group of jack-the-lads so we have to be on our toes. As one of the recognised 'senior figures', a witty put-down enough to take the wind out of their sails always does the trick but I have known it get out of hand. Older heads shout expletive-loaded advice as to what will occur with the long arm of the law if they persist and that will mean our allocation is reduced. We ensure they are aware we'll make it known who's responsible and that tends to work. Racism is just not on at all and I haven't heard one solitary racist comment for about a decade.
