“Thugs have their origin in muslim India.”
India has numerous deities. Most people do not know that it was the British Empire that wiped out Thuggee in India.
Calling these criminals “thugs” is proper American usage, but the original Thugs were far better organized and vicious. They viewed killing others as a sport and a sacrament, and they had elaborate procedures to allow them to get away with it. They may easily have murdered a million people over the years in India. Your wikipedia source has it right.
