Of course this is a difficult subject matter and the way he presents it to us is (unfortunately) the way it happens... it's shocking but true - people turn a blind eye and do not want to get involved. That's why I think it's a a very powerful song.
To be quite honest I'm not British and did not know about this...the same way I did not know about the Moors murders until I heard suffer little children. I, for one, really like this song and the lyrics.
I don't think you need to be British or Irish to get it. Child abuse happens everywhere. Morrissey is just using an incidence he knows about.
