I think that you are the one that has: "............clearly made your mind up?"
You say "................in his eyes he wasn't meeting or discussing with the IRA but a political group............"
That is, IMO, a shameful 'dressing up' of reality - you cannot really believe it, you must just be continuing your denial.
But OK - let's give it a go - so the logic of your stance here is that his actions were in fact legitimate because he was interacting with 'politicians' - have I got that right?
OK, so when he stood observing a minute's silence for the death of 8 IRA terrorists - how does that square with your reengineering of reality? Did he not know that they were terrorists?
Did he not realise that the 8 IRA members killed were notorious for targeting and murdering British civilian labourers carrying out building work on NI police stations??
Did nobody tell him that they were actually killed during one of their many gun and bomb attacks on these installations??
How does that square with your claim: "................that doesn't mean he ever accepted or condoned their (the IRA's) actions."
