Hate to pull flumpf into this but there is a parallel here.
She won her first election to become prime minister due to a widely despised labour government who had fucked up the economy. The leftist political/media establishment, thinking this was just a fluke that could be easily undone, began loudly declaring her to be cartoonishly evil and incompetent at every opportunity with the expectation she would lose the coming election....then she won.
Thus they doubled down and went absolutely apeshit in using every platform they had influence over to communicate to every person in the country how uniquely satanic and monstrous she was and how she was turning bongland into mordor and was going to cause nuclear war and concentration camps and such, certain that with every imaginable media source from news to music to doctor fucking who declaring her the antichrist she would *definitely* lose the coming election.....then she won
again.
Worst of all, after this second victory the apocalypse they promised if she won not only failed to show up but the economy took off again and the cold war ended with total western victory and her in one of the main big boy chairs claiming her generous share of the credit as the iron lady, thus vindicating her domestic and foreign policy keystones and delivering a truly biblical humiliation to a leftist circlejerk whose smug predictions of the UK becoming a destitute third world country were matched only by their unsubtle drooling over the USSR and the communist dictatorships it propped up.
In the end they never even got the closure of eventually defeating her an election or two down the line given how her underlings overthrew her, thus letting her walk away electorally undefeated with a place in the history books as the PM who led britain through the end of the cold war, who presided over the reversal of its economic and geopolitical decline, and who made the labour party and wider opposition her personal bitch for eleven years
.....and all this for a leader who frankly was never particularly charismatic, intelligent, or competent, let alone good. She just stuck to a few somewhat intelligent policy guns and loudly talked shit about how much the opposition sucked donkey dicks, and it worked a charm because it turned out the rest of the country were fucking sick of them as well.
They were so obsessed with convincing everyone she was super-duper evil and stuff that they never stopped to consider how much it made them look like unhinged lunatics, especially when the insane shit they predicted failed to materialise. They got so carried away with their mindless hatred towards her that it still poisons the labour party even today given how corbyns campaign was heavily influenced by the old anti-thatcher demagoguery and was delivered its worst results in a century last year.
This is the source of why the most uncontroversial shit she is associated with gets loudly declared as crimes against humanity, from
allowing soldiers to shoot back at terrorists trying to kill them to
sinking ships of nations that declared war on you and tried to annex your inhabited territories to
not letting unelected trade unions of dead industries keep shutting down the country, and even today you will get people who were born ten years after thatcher left office foaming at the mouth about how she was literally hitler.
Hating her became an honest to god cult in bongland media circles and in the corbyn tier wannabe revolutionary political/activist sphere, and may well be one of the few things these champaign socialist speds genuinely get angry about given how badly her tenure humiliated them in the eyes of the public.
