Black and Tans, the famine, hedge schools, the Easter Rising, the history is long and ugly re: English terrorism toward the Irish.
But re: this meeting, GooseyLoosey's post is more to the point. We're talking about recent, personal, living memory here when we talk about what the Irish have to forgive and move past - Bloody Sunday, internment without trial, lack of access to housing and jobs, and the countless daily indignities, humiliations and intimidations that occur when you have tanks and soldiers on the streets every day.
The Lord Mountbatten connection surely makes this gesture personally painful for the Queen. But do you really think that McGuinness lived his life in Derry without being close to anyone who was personally affected by the atrocities carried out by the British army?
I hate violence, and I don't think that murder is a legitimate way to make a political point. I also don't think it's a legitimate way to keep people suppressed and too afraid to come out and demand their civil rights peacefully (see Derry on 30 January, 1972. and while you're at it, see the more than three decades of lies and cover ups and justifications of that terrorist act, most of which hinged on slandering the innocent victims).
They are both guilty of the terrorism that they sanctioned by ordering it, or by remaining silent on it when it happened in their name. But the handshake is a good thing. I'm all for moving on, but the notion that it's the English that have more to forgive is just plain galling.
