Margaret Thatcher is dead, and while conservative MPs in England are busy working on her beatification, others are dancing on the streets celebrating her demise, a reaction that in turn has provoked moral outrage and has been called "disgraceful", "despicable" and "totally morally wrong". But is it really? Why exactly? Because Thatcher was such a good person that she doesn't deserve people celebrating her death, or because it is generally wrong to rejoice in anybody's death?
