Dude needs to look into who Margaret Thatcher was and her politics. See how much that gums up his brain gears, because, even outside the fact she was a woman, she was a conservative's ultimate fantasy.
To give three things off the top of my head that might make modern Cons sour on her: She accepted the science on climate change, wanted the UK in the EU, and ceased arms sales to Israel in 1982 due to the invasion of Lebanon.
She's not culture wars enough for them, even if she was economically ruinous, just as they desire.
What they really want is a Thatcher Mechagodzilla who spouts all the culture wars lines they want, has huge stomping feet that kill poor people, and fires detransitioning lasers from its eyes. It can also be AI powered and take away the need for any thinking or education at all.
Not all con states want to secede from the union, but then again they're not islands, so that one's hard to gauge.
Also, most con politicians here were very invested in remaining in Europe right up until we weren't. The promise of a referendum was a hail Mary to try to win the votes of a particular contingent of voters. They got the votes, but never expected the referendum to go the way it did. Leopard, meet face.
Now they're having to pretend it was the intention all along. Make the best of it, etc.
There's also an argument to be made that her stance on climate change was entirely because of the desire to hurt the workers of the fossil fuel industry, especially one in particular, which outweighed all other priorities.
The Israel thing I don't know too much about, but I can be virtually certain it wasn't about protecting the people of Lebanon from a bully.
