I had caught a whiff of it in the past. Certain people considered him to be a terrorist I believe. Though I was under the impression that his wife did a lot more of the militant stuff than he did because he was limited by being imprisoned for so long. Those are the only scraps I can remember.

Oh, and I want to say Thatcher might have openly called him a terrorist at some point. Not sure.

Still though, it was still mostly speeches and civil disobedience, in the grand scheme of things.
