Utterly abhorrent and just an excuse for attention seeking yobbo antics. If the marches are banned, though, oh, what martyrs they’ll become.
I honestly think the best thing to do is laugh uproariously at the ridiculousness of these marchers and their flutes. I recommend having half a Guinness and settling down with the ‘marching’ episode of Derry Girls, which is just joyful and total genius.
(But I do agree that effigies of migrants, or anyone, really, is something that should be clamped down on.)
