I'm fairly indifferent to it, she hasn't had power for a very long time, I wouldn't wish her well but I was mostly too young to understand what was happening when she was in power. My parents generation thought her to be as evil as they come.
Her treatment of the hunger strikers in Northern Ireland was wrong in my opinion, on two levels. She allowed them to become martyrs which is never smart, and she allowed them to starve, whatever they had done they deserved to be treated as human beings. Though they could have ended that themselves at any point and they were criminals, though at least then their organisations had proper aims, while now they are only out to smuggle fuel and drugs. They may have believed they were fighting for freedom but they murdered innocent people and were definitely criminals.
Worse though was her comments on Apartheid and the ANC, calling Mandela a terrorist. She was wrong on that score.
Though I suppose one mans freedom fighter is another mans terrorist.
As for what happened in the North of England and Scotland. She gutted communities, but perhaps for the long term good of her nation. I can't say she was right or wrong on that, but I can understand how it might have turned peoples opinions against her.
