No, not in a modern civilised society but I think this is happening in Nornireland.
Unfortunately Scotland has more than its fair share of these imbeciles as well.(On both sides of the religious divide.)
Many summer Saturdays in Central Scotlands town centres are thrown into chaos by grown men dressing up,banging drums and pissing in the street.
IMO all marchers from both sides should be put into Hampden Park to fight it out and the survivors shot as they leave.
This would do a lot to improve the average intelligence level of Scotlands population.
