"FInd me a supporter of TGL under 45..."
Well, for starters, TTT, there's one right here. At least partly, at any rate.
If you are going to set such store by personal experience, then my having recently had essentially a lifetime of state education ought to count for something. Oh and on top of that I went back to the same school and have taught there myself. When I wasn't busy explaining the virtues of Lenin (oh, what a giveaway!) I was mostly teaching them maths. As were most of the maths teachers (with one notable exception, but that's a whole different story). There was a sense of frustration at yet another un-necessary overhaul courtesy of Govey, but such as it was it was kept in the staffroom.
Any indoctrination against Thatcher takes place at homes; homes of embittered miners, etc etc. Shame they don't treat Scargill with the same disdain, but I suppose that isn't too surprising.
