I don't know if religions can really be blamed for the actions of man. Religions are just abstract ideals and stories made up by people. The use of religions is totally up to the individual themselves. Religions do not act, religions cannot act; only man acts. Any given religion can be made violent and any given religion can be made peaceful. It's all how the individual chooses to act. If not religion, we'll come up with other excuses for our actions; it's not like religion is unique in this charge.
