Even though most muslims and christians do not take active part in terrorism, but almost all them believe in killing and torturing humans as sacrifices. Because of that most of them keep quite, and even look for excuses, when some of the members of their religion get caught.
Both of these religions are not outdated. Their numbers are increasing every day, some through open conversions, and some through secret conversions.
In the last 300 years christians have murdered atleast 200 million people, and muslims atleast 30 million people.
