There are two ways of looking at this -
outrage, because both sides represent the respective sides of a historical conflict that has lost thousands of lives and caused untold misery, so a meeting like this should never happen, and we can go on mistrusting each other, with the smouldering embers of conflict ready to flame at any time, or ...
reconciliation, because big changes in minds and attitudes come from small but significant steps, and this is one of those.
Hatred and conflict have to end, and the way to end them is for both sides to recognise that they have played their parts, and they have to move on, personally and nationally.
I applaud Charles for his ability to swallow his hatred and distrust of Mr Adams and all he stands for, and I applaud Mr Adams for putting aside generations of hatred and distrust of the British establishment - both in the name of keeping the peace that we now enjoy.
It's useless to hang on to old hatred, it only hurts the haters.
This is a way forward, and I think it is wonderful news for everyone.
