OK, so you've become all too familiar with the Bush-Hitler equivalence and may be wanting something fresh. Want no longer. I bring you the Blair-Saddam equivalence. How so? Thus so:
Being evil is perhaps to be defined as killing more than 10 but less than 500 people? Below that level, you may be a psychopath, or have understandable motives. Above it, you are a statesman, unless you are on the wrong side, in which case you are a genocidal tyrant.But who is it talking about Tony Blair in these terms? A loonyloony of the Loonyloonyinnit Party? Why no, only Professor Steven Rose and in a would-be serious article for the Guardian Life supplement. You see, Blair is like a genocidal tyrant but for the fact of not being on the 'wrong side'. Which just goes to show you that being an eminent scientist is no more a guarantee against flipping your lid (loosely speaking) than being an eminent playwright is.
That apart (Mrs Lincoln), the issue discussed by Professor Rose in the article aforesaid is an interesting one.
