From The Telegraph:
The anti-Thatcher anthem Ding Dong the Witch is Dead has seen a surge in popularity since Baroness Thatcher’s death and looks set to retain a top slot when the Official Chart Show airs on Sunday.
Partly their support for the Wizard Of Oz song might be down to the fact they know "the left" are currently making themselves look mean spirited and nasty as they delight in the death of a person but more importantly it's consistent with "right wing" ideas.In a controversial move the BBC are likely to play the track if it is in the top five, after executives are said to see little reason to take it off of the airwaves. A final decision will not be made on grounds of taste or decency.But the move has found support in some unlikely corners as UKIP leader Nigel Farage and Tory MP Philip Davies, who have both paid glowing tribute to the former leader, said broadcasting the song was the right thing to do.
I classify myself as neither left wing nor right wing but I'm astounded that no one on Thatcher's side has yet to think of the obvious response to all this: buy Telstar next week and the week after and the week after. It's famously her favourite pop song.
 Why would that be? I suspect the left wing are less inclined towards free speech because one of their core ideas is that all people are born equal, as a blank sheet of paper, and their characters are written upon them by the events of their lives. The right wing tend more towards the idea that people are born fully formed and genetics is the main factor in determining who you are. If you take the left wing "tabula rasa", or blank sheet of paper, approach to life censorship makes perfect sense. You can't let bad ideas get written on that paper! If you go the other way and think it's all genetics then what harm is there in someone seeing or hearing something offensive?
Evidence to support this theory comes from the left's advocacy of Leveson. More trivially you can see it in the comedy world in this interview in The Guardian with the creators of South Park:
"The big lie of our whole career is that rightwing fundamentalists are always trying to shut us down," Stone says. "It has literally never happened. The Mormons haven't, the Christians haven't – OK, the Scientologists did, but they don't count. But when we make fun of liberal people, they're like, 'What?!' I think religious conservatives are more used to taking a beating." And as if to antagonise their long-suffering liberal fans even more, Parker announces that the two causes he and Stone believe in are "gay marriage and guns. We're for both of those."
