Interesting point, mcmoo. Here in the U.S., I can't recall ever hearing a song from the "Orange" point of view. It seems there is a spirit among some of those who enjoy Irish music of "Let's rally behind the (Green) Irish", akin to the St. Patrick's day feeling of "everybody's Irish today". While I'm sure many don't have any real political convictions on the matter, and simply find the song entertaining and perhaps informative, there are others who are indeed partisan and take it rather seriously.

And as you say, this may be part of the problem. It's like the philosophy behind advertising--if a message is repeated often enough, some of it is bound to sink in. I would guess that in Ireland, particularly Northern Ireland, one might indeed fan some flames of ill will with such songs. Over here, the effect is muted, and I would like to think that I'm not propagating any hatred with it, but--you've given me something to think about.
