Your second sentence strawmans the article. Nowhere do I say that Muslims are inherently immune to comedy or that they lack the comedy bug as humans (at the genetic level). Nor am I talking about every single Muslim "collectively," without exception.
This article is part of a series. In "The Satirical Gist of the World's Religions," I point out, in the case of Christianity, that "Not all Christians were clueless about the comedic purpose of the Jewish side of their hybrid religion. The Gnostics got the joke; they took to heart the psychological depth of the metaphors." And I say "the Western religions all have esoteric, Gnostic traditions, including Kabbalah in Judaism and Sufism in Islam."
So I'm fine with saying there are exceptions, including elite philosophical, mystical, or literary traditions in Islam that aren't so fixated on the letter of the law to the point of being in favour of killing folks for blaspheming Islam.
But I'm generalizing here about the cultures of the Muslim world, which are united in taking blasphemy to be as about as bad as apostasy (a form of unbelief).
I'm afraid you give the game away with your admission that "the taboos against blasphemy are stronger than other Abrahamic faiths, but even this law was never followed universally." It may not have been applied universally, but it was applied. So Muslims were punished for mocking their religion because this mockery was conflated with apostasy.
Even if this law wasn't enforced, having a law on the books can have a chilling effect.
In any case, all I'm trying to explain is why Muslims have prohibited "blasphemy" or mockery of Islam to this extent (having such laws at all, and prohibitions in the hadiths). Specifically, why the difference between Jewish and Islamic cultures on this point, given their shared monotheism? This is a mystery that cries out for explanation, and quibbles about exceptions (about Muslims who slip in sly comedic criticisms here and there) won't affect the overall point that you conceded.
You say all cultures have sensitive areas. Sure, but when was the last time you saw Jews all around the world rioting in the streets because someone insulted Anne Frank? Spare me the false equivalencies, please. Your reference to "Eurocentrism" suggests you're coming from some kind of woke standpoint, which would account for the lame excuses you're making and which would be a shame.
But I appreciate the substantive criticisms.
