Personely I don't think too much of the IRA. Because of some of the targets. Like how about the school for the army band? What is that supposed to prove? That guns are stronger than trumpets? I don't know all the history of who did what to whom. I think that some parts of the world just don't get along very well. Iraq and Iran, for example.
Anyway, I don't think the song is all that bad. Sounds to me it was written by somebody who had just about all they can take, and are not going to take it any more. In his place, I'd probably do the same.
Say for example, Canadian police came to your town to "keep order" (This is only an example, not ment to slam Canada.). Then things get a tense. People have a tendency to react. Sometimes inocents are hurt in the process. This esclates the tension. etc. etc. till the lid blows off.
I seem to be meandering. The basic point is, post the song. I think if all the songs were removed that tried to influance someone, all we would have left would be Puff the Magic Dragon, and perhaps the theme from Tele-Tubbies.
Or folk would start sounding like the Nashvill version of Country and Western. Neither country or western but some sort of beer drinking, crying, achy breaky BS.
