Yesterday I heard an item about this on RTE radio. From an Irish point of view there were a few comments about :

Our nation survived through many storms and many wars
We've opened our doors, and widened our island's shores
We celebrate our differences with love in our hearts
United forever, never apart

Patronising, ignoring the truth about imperialism, racism etc etc.

So yes, let's blame the song as well for a message that ignores some hard truths.
