Can people stop going on about her "conviction", "principles", "strong leader" etc? On their own, these things are NOTHING to be celebrated. Hitler, Mussolini, Pol Pot, etc.
Would you really want David Cameron to have MORE conviction behind his wrong ideas? Take them further, to their extremes...
To them, she's probably on about the same level as Hitler. Playing devil's advocate, would you have a problem with someone rejoicing at Hitler's death?
