Andreas,
If you listen to Billy Connolly explaining the reasons for him writing the song, I think you'll change your opinion as it definately is about Ulster and he definately means children.
Having once inadvertantly got into a pub conversion with a squaddie just back from a tour of duty (this was back in the 70s), I was told that it was tactic of the IRA to hide behind rows of stone/rock throwing children, against which the soldiers could do nothing.
Cheers
Mick
