admit a conservative like Thatcher was right.
I've been a "left wing greenie" since the 70's, my 80yo parents are both life long "war baby" conservatives who grew up under Winston Chuchill, I love my elderly parents, I don't agree with everything they say but that doesn't make me hate them? I'm also old enough to clearly remember the 70's and 80's and I think you are correct, Thatcher deserves credit for pulling the UK out of a bad financial position, even though her methods polarized the political landscape. It should also be noted that "trickle down economics" has also ultimately been discredited by the recent GFC but you can hardly blame Thatcher and Reagan for the extremes of deregulation implemented by others that followed their tenure. For example, here in Oz it was the left wing treasurer and later PM (Paul Keating) who pushed for deregulating the banks.
Having said that, Thatcher, Reagan and Malcom Fraser (Australia's late 70's, conservative PM) were not even the same species as GWB, Palin, and Tony Abbot (current Oz PM). For example Thatcher was the first world leader to publically acknowledge AGW is a problem and Reagan personally sought and obtained an international cap and trade treaty on sulphur emissions that has been very successful in curbing acid rain. I suspect Reagan was taking his cues from Thatcher on the acid rain thing since she had read chemistry at Oxford before becoming involved in politics. Fraser's "radical" policy on refugees was closer to today's green party policy than it is to either of the majors who currently are so close to each other that the only meaningful debate on the subject is which third world nation should host our immigration gulags..
Aside from the fact that ALL leaders make good and bad decisions, celebrating the death of anyone pretty much makes you a douchebag in my opinion. Headlines such as "Ding, dong, the witch is dead" were a low point even by the UK's notoriously low tabloid "standards". Far right conservatives flying an upside down flag after Obama's election were equally obscene.
Liberals hate conservatives
The real problem is human nature, ideas and long term results are simply ignored because people pigeon hole others by whatever political colour they wear on the outside. This stereotyping separates people into political "football teams" and you're not suppose to just enjoy a game of football, society expects you to be a one-eyed supporter of a particular team. GWB summed up that attitude succinctly with the infamous words addressed to the entire planet - "You're either with us or against us". That anti-human attitude, wherever it raises it's ugly head, is what I "hate" about politics.
Disclaimer: I don't claim to be anymore immune to the tribal nature of humans than anyone else on the planet, however just being aware of it's existence does make one stop and think every now and then.
