all religions have the same essence, Islam is the same monoistic religion as Christianity, Judaism.
I do not think that Islam calls for violence. it so happened that dishonest people covered themselves with religion to make themselves holy in the eyes of uneducated people. and generally made religion a cover. except money, they have no other interest, at least those who rule this terrorist gadyushnik. and fanatics-it's already excuse, people with deviations, which can be found everywhere. led full full. Look at how many people fall into sects around the world. and this is the same sect where the brains are washed.
but real Muslims, they are spiritual people who preach the same covenants of kindness and love that are preached by Christians.
