...I'm not a muslim nor am I defending them. I'm against the fact of this discrimination between religions as I know extremist groups within my religion too. I'm just saying that no religion teaches people to kill others (as far as I have learned about the holy books). It's these inhumans who try to interpret their holy book and preach cruelty. I don't know which schools are you talking about that teach muslims to kill (it may be those schools of colleges that exist within those terrorist states (ISIS mainly). Rest such schools aren't allowed to operate outside.
