Are you opposed to communism? Then you're anti-communism. Are you opposed to Nazism? Then you're anti-Nazi. I oppose islam in all forms and will do my part to ensure its annihilation. Being tagged as anti-islam is a badge of honor.
One can be either pro-islam or anti-islam. Destruction of this satanic cult demands nothing less than plain speaking and clearly identifying islam as the enemy.
The trouble is, while they are identifying this event as "anti-islam", they are also identifying Islam as a "religion of peace" rather than a blood thirsty murder cult.
