I see your scrimshaw and haberdashery and I raise you "zakatability".
MOO, there is clearly a misunderstanding going on here as to who is paying for the bulk of --Islamist efforts in the west including peaceful and non-peaceful efforts-- I was hinting at Saudi Arabia and Iran and their fellows.
ETA: oops- had zakat on the brain and mistyped. All Muslims do pay zakat when they are not under hardship themselves, which Richard referred to. But not everyone is a great Muslim, either, especially the rich international Muslims.
