So, no one is allowed to like her and show their support at this time, or feel indifferent, just because another group are filled with dislike and hatred?
That's not how our society works, so please leave it out. He's entitled to feel however he likes about it, as are you.
You say that what we are going through today is linked to Thatcher. I think it's a rather tenuous one at best. Sure, she started a big shake up in this country to how things were before, but her leg finished around 24 years ago. That is a hell of a long time whether it's in politics or not.
As for linking her to the problems we face today, this is highly debatable. One of the reasons we are in our current situation is that we now have such huge public borrowing and debt, where as in Thatchers day it was just private borrowing. It was never a Thatcher policy to borrow such a high amount. Our countries debt mountain has absolutely nothing to do with her. Neither can we blame her directly for allowing the banking crisis to happen. This public debt is mainly the work of Brown and Blair, as was their cosy relationship with the financial industry also a factor one must presume for them not being regulated by the FSA in a proper way.
At the moment we look to be heading back to a similar situation that we had in the Seventies. Currencies being devalued and high inflation. The government can't deal with the massive public debt through austerity, so the only way it can clear it's debts is through manipulation and taking from its citizens - all of them. Devaluing of our money coupled with high inflation has the economic effect of eroding debt.
