This is an excellent list of specific examples, but I think it fails to really capture the overall tone of Thatcher's leadership.

I don't think it is in any way an exaggeration to describe her government as fascist. Her rhetoric leaned heavily on nationalism. She spoke glowingly of the British empire, dehamunized the Irish, and treated the working class an enemy to be defeated. Her MPs spoke openly of their desire to see queer people eradicated. Under Thatcher policing in Britain became open warfare. She endorsed and encouraged every vile and base instinct of her conservative base. To describe her as the British Donald Trump only fails in one aspect; unlike Trump, she was often terrifyingly competent.
