That’s not the issue. You hear plenty of commentators say ‘they’re too young to remember the troubles’ and ‘we don’t want to go back to those dark days’ whilst completing ignoring why these people exist.
Most people involved at the start of the troubles weren’t around in 1916 or the war of Independence, and they weren’t about for the Fenian Uprising, and they weren’t about in 1798, and they weren’t about during the Confederate Wars and they weren’t about during the Nine Years War. All this goes back to English/British occupation on the island. As long as there is that presence, then there will be resistance to that. Got fuck all to do with being too young to remember shit it’s in the psyche and it won’t go away.
