I don't know much about Thatcher, but I tend not to like what I have heard. However...

In the past, the schools of the United Kingdom were the laughingstock of the western world, people died from breathing the air in London, the Thames was an open sewer, and unemployment and recessions prevailed for years. Yet the men who governed then have never been subject to the nastiness to which Thatcher is subjected.

I don't think it's politics, I think it's jealousy. You are angry because a woman got to a high position. Worse yet, she was a woman and she didn't act like the national Mum! Isn't that it?
