'And I wish that my rifle had given the same
To those traitors who sold out the Patriot Game.'

I always took it to refer to wanting to shoot the Michael Collins contingent, who made the peace 'selling out' the six counties. This point of view of course would (presumably) get the approval of the IRA.

However, I don't pretend to have a deep knowledge of this complex subject, and from experience of Mudcat, I know any expression of opinion on this subject is bound to enrage someone.

so, whoever I may have offended, I apologise in advance.
