But without that, how would you justify that as the only violent struggle that worked? They didn't achieve a united Ireland. No offence to the IRA or Sinn Fein obviously, but the Good Friday Agreement wasn't considered a resounding victory in my recollection, and led to the Real IRA splinter group.

All of human history and that's the one time violent struggle against oppression worked? Assuming their American they can't even remember their own bourgeois rebellion?
