Regarding violence or the threat of violence, as practised by Pearse, Carson and the rest, I'm afraid you're stuck with it. Why? Because it can work, that's why. I could give you a rational for both Carson and Pearce, but ultimately it was the use of force (or it's threat) that triumphed. That my friend is the way of the world and I would suggest that 'democracy' is particularly vulnerable to it. If these types fail, then they're scum, but if they (or their cause) succeeds then statues are put up to them - often by 'democrats'. LOL
As regards your final point, you might well have been right. Or perhaps you may yet be right?
