dear oh dear where do i start with Mrs T?
how about the wholesale breaking up and privatising of British Petroleum, British Aerospace, Britoil,British Telecom, the buses, British Gas, British Airways, British Steel, Regional Water Authorities, and the National Grid
for someone who was so fiercely patriotic she had a strange way of showing it - selling us down to river to foreign investors
how about the Falklands? an insignificant little backwater none of us had heard of until Argentina decided to reclaim it - indeed her government refused to grant full British citizenship to the islanders as late as 1981, giving Argentina a green light (an Argentina, incidentally, armed by Thatcher - she had a love of South American dictators when it suited...Pinochet, Galtieri) a war fought solely to bolster her polls and return her to power.
Did you love the 18% interest rate or the 3 million unemployed that it cost to recover?
Her support of apartheid in South Africa (Mandela was a terrorist, eh Maggie?)
Remember the Poll Tax?
The riots, the strikes?
yep - she was a great leader 
As for the breaking up of the utility companies, do you remember the time when it took 3 months + to get a phone installed ?
Falkland Islands- there are many places like this which we the general public don't think or no about until a problem occurs.
Interest rates- yes they where high at times.
Unemployment 3 million eh, well just think what it really is today 2+ million officily today with numerous ones moved over to disabilty benefit to hide the figures, then don't include under 18s etc. I would estimate the real level to be about 4 to 4.5 million today.
Mandela a terrorist- well look at the facts, both he and his wife where suspected off being involved in a murder. And rightly or wrongly the law at the time found him guilty. wether that law was wrong is for better people than me to decide.
The poll tax, my favourite. This was fantastic, my aging last grandparent paid about 10% of the poll tax because it involved the ability to pay and how likely you where to use the services. All the poll tax did was make those pay who should be paying, and saved our pensioners and vulnerable people a bit of money.
The riots and srikes, riots can't really comment as they did not happen where I was living. The miners strikes, depends on what side of the fence you sat. But the arthur scargill should take 99% of the blame for the miners strike. He was demanding that the pits stay open regardless of cost. Is that feasible ?
She was needed a time when the country was in desperate trouble. under the previous labour government, the unions arrived at 10 Downing Street and told the prime minister what they wanted, and if he did not agree, half the unions came out on strike.
