I cannot think of any post WW2 UK PM that can induce such levels of polarisation of emotion, adoration or hate, as Thatcher. Not Blair. not even Brown, although i am sure that there will be people who dislike or even hate them intensely.
Of all, Blair is probably closest to it, with the Iraq War, allegations of croneyism etc, but of all post war PMs, only Attlee and Thatcher truly changed the political landscape.
And of course, as you say, we all know that right wing supporters never ever descend to insult, or childish or violent or tasteless behaviour - they are far too superior for that...
I cannot see any of the now living ex-PMs being afforded the honour of what amounts to a state funeral with all that procession and pomp, at the taxpayers expense though, can you?
