Are you ready to curse Oliver Cromvel, the crime and murderer Fransis Drake, The king Henrich VIII as your shadowy past? Cromvel was real tyrant, squashed Parlament and human rights. I want you to repudiate them. It was your mistakes in the history, that you allowed to rule (or to be close to Quinn Elisabeth) such people. Fall down on your knees and beg for pardon!(The last sentence was written in jest:)<quoted text>
There are various degrees of acceptance.
A) You can accept them, praise them and make new leaders in their mould.
B)You can accept that they were badly wrong and bury your head in the sand.
C)You can accept they were bad and correct your notions so that bad mistakes are not repeated.
Of which British tyrants do you speak that are accepted?
And I will cite the good qoutation from one great Soviet film. Sorry, in Russian: "Ne uchi uchionogo, grazhdanin Kopchiony!" Translate it yourself.
