Irony, I think, rather than sarcasm, but point taken.
Words have meanings. "Simple fact" describes a statement of uncomplicated, empirically-verified truth. You claim, "that any Arab leader who had Sharon's human rights record would have been given the Nobel peace prize five times over", is nothing of the sort. In the first place, it is an exaggeration for rhetorical effect, that much should be plain even to yourself. In the second, the claim it expresses, that a Palestinian leader who behaved as Sharon did would have a more positive reputation, is not an empirically-verified truth, but simply speculation, a "what if?". You might be able to find empirical evidence to support the claim that that Israeli leaders-in-general are held to more stringent standards than Palestinian leaders-in-general, but that's by necessity a generalisation, which can't be used to prove or disprove claims pertaining to any one individual, much less an entirely hypothetical one.
So when you say "simple fact", what you in fact mean is "complicated fiction", and that's just not the same thing at all.
Oh, I see. You were discussing the semantics of my statement rather than the actual subject at hand. For future reference, I believe it is called "hyperbole."
However, I think it does raise a good point. Why don't you apparently find the Israeli government "accountable to the same standards" as other governments in the region?
I don't follow this sentence.
