Just catching up with this thread.
LDNmummy - did you see the film yet? I saw it at the weekend - I didn't think it did glorify her, quite the opposite. The trailers that have been on TV are a bit misleading I think.
Several posters have remarked that she was bankrolled by a rich man. Yes. Unfortunately, so were and are many others in politics, including on the left. In the same vein many successful businesswomen got a start because they were bankrolled in some way too, even if they've now paid the money back and are standing on their own two feet.
To take another example many successful female authors/journalists or indeed film directors (thinking of the film which has inspired this thread) are or have been supported or bankrolled by their other halves in some way too.
(By the same coin) a 'roll back the state'-type Tory might point to women on maternity leave and claim they are being bankrolled by the state
I say all this not as support for Margaret Thatcher but to point out, as others have, that some of what has been said here is not really Maggie-specific.
