Which God? There are thousands, maybe even millions of Gods, each having a different set of ideals they want followed.
In Islam, by following the rules and fearing nothing else other than Allah ( fear because he can destroy you if you don't follow the rules and fear leads to obedience. That Fear leads to obedience part only works for omnipotent beings)
Race matters less than beliefs and practice.
The extreme example is that radicalized Muslims do not think of "western" Muslims as Muslims ... Due to their "relaxed" practices. (Things like women not being covered properly)
Yes we do obviously.
We acknowledge all other humans... Muslims or not.
