Suffragettes actually killed a small number of people in a bombing campaign....allegedly being the inventors of the letter bomb.
What the Suffragettes did was far more destructive, disruptive and as you point out, some reports do suggest a couple of people died due to their actions. But they’re now seen as pioneers for women’s rights. Honoured and lauded by female MPs for example only last month.
I believe that the suffragettes tried to blow up Lloyd George's house at some point. So while I agree wholeheartedly with you on your thrust on this thread we need to take some perspective and context into account. Fundamentally I think the definition of terrorism needs more careful thought. Yes, there's a terrorism law which suggests damage to property is 'terror' but it also raises the question of where one draws the line. I damaged property quite a lot when I was a kid because I was a twa.t. I'm not suggesting I was a terrorist by doing that but there are some organisations that do that more methodically (Just Stop Oil etc). Is Just Stop Oil a terrorist group? On Palestine Action I dont think, in my world view, they are a terrorist group even given the 2000 law. Firstly, I think their actions are more vandalism than terror if one looks at their history. Second, the government's own advisory body advised not to describe them as terrorists. Third, in the quarter of a century since this law was passed Palestine Action are, I believe, the only group to be proscribed for attacks on property/assets. So, as I said, in context this looks like a politically motivated proscription of a group that is much less violent, regular and consistent in its actions than some other groups. So, from that, for me, the government is manipulating the terrorism act for political purposes, not for legally ( or moral) grounds. The government is therefore corrupt (because of links to Israel) and/or immoral or stupid. Palestine Action, basically, is not a terrorist group. And, referring back to the Suffragettes, they would definitely be proscribed by a) the 2000 law and b) this Labour government.
