Between 1980 and 2005, 94 % of all the attempted or Successful terrorist attacks on US soil were not carried out by muslims radicals but instead by non muslim white guys...
As one bloggers correctly points out..
If the person who killed 100+ people in Norway was Muslim, the Press would have declared him as a terrorist. For now though, he is just an 'Assailant ', 'Attacker' (Reuters), 'Gunman' (BBC, CNN & Al Jazeera). Looks like 'Terrorist ' is a name reserved for Muslims? The US Dept of State calls it an 'Act of Violence', Not an 'Act of Terrorism'.
