As an aside, camels get slaughtered here every day...I had camel meat for lunch just a few days ago. Tastes like roast beef, a little stringier, perhaps. It did nothing to change my opinion of the Avro.
Islam, by it's very nature is radical. Adherents love to say that it's the religion of peace, but the Qur-an in some of the first Surah (verses) calls for the death of the unbeliever, or for any who would reject Islam. Islam, by definition, is the worship of Allah as the one true God, and Mohammad as His messenger. Infidelity to Islam, by definition, is unbelief, or refusal to believe, in Islam. The Qur-an is considered perfect, without blemish, and the word of Allah. Under Sharia law, prescribed through the Qur-an, the unbeliever infidel is subject to the "fire of Allah, whose fuel is men and stones."
Sounds radical to me.
In Islam, any who don't speak arabic, or who do not read the Qur-an in arabic, fall to a lesser state; Muslims believe, especially arabic muslims, that the true language of Allah is arabic, that the Qur-an can only be properly understood in arabic, and anything else is a step down.
Under Sharia law, the life of a non-muslim is worth only half of that of a muslim. Says a lot right there. The fact that one of the few crimes always worthy of death is nonbelief or renunciation of one's belief in Islam, also says a lot. Radical, no matter how you slice it.
Having said that, I think one would be hard pressed to suggest that sacrificing a camel, or celebrating by killing a camel, represents extremist or radical activity. It's a traditional thing in this neck of the woods. Ever hear the parable of the prodigal son, and killing the fatted calf? Same concept.
