Love that people can fall back on this now. You're faced with two groups of nationalism, Irish republicanism's solidarity with workers and the oppressed versus the UDA's colonial legion of doom with their murals of Catholics being stabbed with the Union Jack shouting "we will kill you". Tough choice, but I'd go with the former. Sorry if that's too controversial for you
Honestly the latter sounds a lot cooler.
Who would you rather side with, the supporters of the empire that owned half the world, or some dirty peasants?
