Christians, like the guy that killed the abortion Dr. commit these acts because of what THEY THINK, the Bible means.
Muslims who commit mass shootings, and suicide bombings etc, are doing so because the Koran explicitly states things like "all infidels must be killed", and "the only excuse for a Muslim to befriend a Christian or Jew, is to deceive them".
Calling Islam "the religion of Peace" is like calling National Socialism the Politics of Peace.
