Yes, but remember there are two lines of descent making up the current Irish Labour Party. There is the nice, cuddly traditional Labour sort who are (somewhat naively in my view) attached to the idea that Government knows best, and we should allow it to run more and more of the economy and society generally.
Then there's the other half of the merger - the line descended from Democratic Left, formerly The Worker's Party, formerly Sinn Fein the Worker's Party, formerly Official Sinn Fein, formerly Sinn Fein. This line maintained its army well into the 1980's for fundraising purposes and was involved in bloody warfare against the INLA and other far left Republican splinter groups. It also maintained cordial fraternal relations with the most unsavoury of Communist regimes and regularly sent and received delegations to places like North Korea.
Oddly enough, the former "Officials" never decommissioned their arms, and yet, they were welcomed with open arms into "respectable" politics. Can't imagine why. It's almost as if they had vast armies of people burrowing their way into the newspapers and RTE
