I can't separate his actions out from the massacres.
Fine. I mean, I can't separate out the beauty of Roman engineering (underfloor heating! aquaducts!) from the murderous actions of the Legio II Augusta… but I understand the historical process involved. 😉
I'm certainly not making light of Cromwell's Irish campaign, but that does not remove from his pivotal role in English politics. It may be impossible to separate out a man from his actions, but history ain't a single-faceted thing.
As for your cuddly pair, I can't separate either of 'em from the bloody turmoil of the last few decades. But things have to move on – surely all can agree on that?
