You gotta ask the aztecs, incas, mayans who were looted by the spaniards and forced to convert. Muslims merely tax the people they occupied. Otherwise, how to provide services and utilities?
Just like how the mafia asks for protection money to protect them from the mafia. Islam is an evil cult and nothing else. The so-called "peaceful Muslims" are just not faithful enough to carry out the real Muslim practice of killing and looting the Kafir.
