As someone who lived in Belfast through the worst of 'the troubles', I too am ambivalent about the death of Martin McGuiness.
When it all kicked off, I was a student and avid supporter of 'one man (sic), one vote'. Only fair in what should have been a democratic society. Catholics were definitely discriminated against in many ways. However, the IRA had another agenda and that was a United Ireland separate from U.K. I am not averse to that either. In process of applying for my Irish passport to remain an EU citizen.
At the time, they chose to roll out this agenda by random and widespread acts of horrendous violence on innocent civilians. Bombs were planted in the early days mainly in the centre of Belfast without any warning almost every day at one point. The city centre was decimated. Men, women and children were killed and seriously maimed. And like you, Coolgran I had several near misses. Some of my acquaintances were not so lucky. Inevitably, it turned into even more horrendous tit for tat civil war.
And Martin McGuiness, Gerry Adams and Gerry Kelly were involved in this. Hardly surprising then that people who lived through this and suffered, are finding it difficult to forget. And Anniebach I know all about the 'freedom fighter' argument. But IMO no one has any right to take the life of another just for idealistic reasons. Not then, not now.
On the other hand, I admired M McG for his strength of character in working for the Peace Process and following through on the agreement. Our current 'politicians' need to emulate them and stop their petty backbiting. So yes I do find it difficult to forget the past. But acknowledge the turnabout he made to bring N Ireland out of the awful mess it was in. The world could do with more of that.
