In my opinion, the walkout and split of the IRA and Sinn Fein in 1986 is relevant to understanding Irish Republicanism.  If the split was not relevant, why did Adams and his supporters go to such great lengths to try and keep it from happening?  This includes asking Tom Maguire for support.  When so many founders of the organizations walk out it is significant; recognizing Leinster House was a watershed.  Adams, if I recall, praised Dan Keating for not walking out, only to have Keating later become patron of RSF. I am not trying to make a mountain out of a molehill, I am trying to have the Wikipedia article provide an accurate description of what happened so that readers are informed. WH.
