" It drives me crazy when "Allah" is translated as "God"."
Christian Arabs were using the word "Allah" to mean "God" before Mohammed was a twinkle in his fathers eye.
And they still do. Those that the Muslim Arabs haven't killed off that is. Now whether the Allah of the Muslim Arabs is the same as the Allah of the Christians, Druze and other monotheists is up for debate. But "Allah" is merely Arabic for "God". One of the main principals of Islam "There is no god but God" (often half translated as "there is no god but Allah"), in Arabic uses allah/Allah for both "god" and "God".
