Yeah, she was right on a lot of issues. Allowed inevitable progress to occur. Made a lot of enemies, and made her own people into enemies.She's loved (or at least respected) because of quite how utterly fecked Britain was before she came into office. A lot of people got hurt during her time in office, and she went off the rails spectacularly towards the end, but the state of the country pre-Thatcher was absolutely abysmal.
Who knows.
