Radical groups promoting FYF 911, a September 11th flag burning movement

A website claiming to belong to organizers calls the planned act, "the most powerful movement in the world right now." It goes on to explain what's planned.

“We, the people, are psychologically and physically breaking free of the imperialist, colonialist, and racist empires by burning representations starting on September 11th 2015.

Why September 11th? We recognize that these imperial powers attacked their own citizens on 9/11 in an attempt to gain more power from its people.

We are not disrespecting any citizen that may have died during these attacks on this day, instead we are acknowledging that, from this day forward, we are holding ALL imperial nations responsible for their needless deaths!

On 9/11 we will be burning American flags, confederate flags, police uniforms, and ALL representations of organized evil and oppressive nations.”
