"There have been plenty of other Catholic NI players at Celtic FC, all of whom were received well by their own countrymen"

Yeah, tell that to Anton Rogan.. Or maybe name us a few 'well-received' Celtic Norn Iron players. Lennon wasn't just 'attacked' - he was put under a death threat by the LVF.

Whole thing reminds me about the Dominic Behan (though he probably nicked it from elsewhere) comment about the absurdity of people in the North (and by extension in Glasgae) keeping going a 300 year old feud between 2 foreign kings that never gave a tinker's curse for them in the first place....
