Dylann Storm Roof, the suspected shooter behind the deadly shooting at a church in Charleston, South Carolina, is thought to have penned a racist manifesto prior to the attack that left nine African-American worshipers dead.

A text apparently posted online by Roof says that the discovery of "black on white" crime changed him. According to the manifesto, Jews also play a pivotal role in Roof's world view.

On the website called the Last Rhodesian – a reference to the white-ruled state that preceded Zimbabwe – Dylann says that though he was “not raised in a racist environment”, he came to develop "racial awareness" in wake of the shooting of Trayvon Martin by George Zimmerman. His investigation into “black on white crime,” he wrote, led him to understand that the African-American community posed a threat to whites in the U.S. and that it was on him to take action.

“I have no choice. I am not in the position to, alone, go into the ghetto and fight. I chose Charleston because it is most historic city in my state, and at one time had the highest ratio of blacks to Whites in the country,” Roof wrote.

“We have no skinheads, no real KKK, no one doing anything but talking on the internet. Well someone has to have the bravery to take it to the real world, and I guess that has to be me."

The sprawling racial tirade is peppered with references to other minorities – including Jews, which he says are an agitating force in the U.S. In his text, Roof says that as part of his process of racial learning he came to be aware of what he describes as "the Jewish problem and other problems facing our race" in Europe – which he calls "the homeland of White people."

In the chapter outlining the essential qualities of the black race, which he describes as both "stupid and violent," Roof claims that African-Americans "view everything through a racial lense They are always thinking about the fact that they are black." Among the reason for this, he claims, is "the Jewish agitation of the black race."

In another chapter dedicated solely to Jews, he claims that "unlike many White naitonalists [sic], I am of the opinion that the majority of American and European jews [sic] are White."

Roof then lays out what can be described as a cultural or social form of anti-Semitism. "In my opinion the issues with jews is not their blood, but their identity. I think that if we could somehow destroy the jewish identity, then they wouldn't cause much of a problem. The problem is that Jews look White, and in many cases are White, yet they see themselves as minorities. Just like niggers, most jews are always thinking about the fact that they are jewish," he wrote.

He also invoked classic anti-Semitic stereotype, saying that the "other issue [with Jews] is that they network." According to him, Jews play a disproportionately large role in the world and "If we could somehow turn every jew blue for 24 hours, I think there would be a mass awakening, because people would be able to see plainly what is going on."

"I dont pretend to understand why jews do what they do. They are enigma," he says.

He also seems to make a reference to Israel and U.S. involvement in the Middle East. In a part about patriotism, he rejects claims by Veterans that "protect our way of life," by saying: "How about we protect the White race and stop fighting for the jews."
