It was one stupid comment followed by another - highlighted by you speaking for 'catholics' when he initially spoke of 'nationalists' as if those are intrinsically the same thing.
@Minimalist was clearly speaking from frustration at the horrendous events this week, lack of progress and mindless violence we still still put up with under the guise of politics - yours was such a typical response for N.Irish people - straight back to arguing and point scoring. Never mind the fact that mere days have passed since the pointless and evil murder, lets jump straight back into the blame game.
Almost as sad as the loss of life is the depressingly predictable slip straight back into the same entrenched rhetoric.
