> to the point that we had arson attacks in Belfast

Not to argue against the point you're making but these aren't good examples. Policing in both Northern Ireland and Scotland are fully devolved and operate independently of the government in Westminster.

True. The modern far right is both a social media and traditional media driven phenomenon, internationally, and I don't have great suggestions for dealing with it other than "maybe the government should boycott Twitter before they ban sixteen year olds from it".
