Please see specific information about the attack in the article UK: Media’s ‘Racist White Supremacist’ attack on Sikh in Tesco supermarket was a Muslim attack. On Facebook, Zack Davies used the name "Zak Ali." Apparently, he used a machete and a hammer during the attack.
Please note that this blog post is not labeled as a "machete jihad" attack. But if is was an Islamic kill-the-infidel attack, would the media state that it was such an attack? Islamophilia rules the day in the the mainstream media. Orwell's Ministry of Truth has arrived.
