Doc, I know you and SadRed are desperate to explain how Islam is not a monolithic block and that not all Muslims think the same about issues like FGM and apostasy. What you don't understand, and this may be why you find discussing this stuff with me frustrating, is that your attitude supports what I think.
Killing someone for losing their religion or loving the wrong person is not an insignificant issue. It's not like wearing the wrong fabric, or not going to prayers. It's the taking of a human life for reasons which are base, barbaric, primitive and usually misogynist. No civilised society could countenance such punishments, and lo, none of you Western Muslims do. But your brethren in Saudi and Pakistan and Yemen queue up to watch the killings or cheer the result, and in Indonesia they offer their baby girls up for cutting and they do it in the name of their religion, which is also your religion.
Terrorists, you can explain. Disaffected youth, American brutality, twisted and vanishingly small section of an otherwise peaceful faith. But when confronted with widespread acceptance and religious justification of the workaday horrors of many Islamic countries, the stonings and the beheadings and cuttings, you cavil and deflect and flounce off only to return and complain some more.
It comes as no surprise to me that Islam condones primitive acts in certain parts of the world. As you mentioned, plenty of other religious people stone women for adultery or mutilate their baby girls. Again, you think this is a defence to what I'm driving at but it's the opposite. The dominant religion always finds a way to assimilate local customs into their shtick. All religions do this, from Christian FGM scum, to Yazidi stoner fuckers, even down to the hijacking of common feast days in favour of something more pious. Religions are populist. It's a clear indication that the message of any religion comes not from God, but from man.
And you will no doubt react to this little screed by reassuring yourself that your nuanced, moderate version of your religion is, indeed, still the one true faith. Of course it is. You made it yourself.
