Obviously, you know that my objection is that in America, God means the Christian God.
If you want the American language to equate God with Allah , you can do that.
There is, in fact, a difference worth defining.
The meaning of the Arabic word "Allah" is the same as the English proper noun "God."
If you want to believe otherwise, you can do that. If you want to exclude Jews, Muslims, Mormons, Baha'i, etc from the American language, you can do that.
Just don't expect the rest of us to go along.
