CHARLESTON, S.C. — A website featuring a racist manifesto mentions Charleston as the “historic” target of an attack and displays images that appear to be Dylann Roof, the 21-year-old who shot nine people to death at Charleston’s Emanuel African Methodist Episcopal Church.

The writer said he was “not raised in a racist environment” and that the 2012 shooting of Trayvon Martin — the black Florida teen whose shooting death at the hands of George Zimmerman, who was acquitted of murder, provoked huge protests — prompted him to research what he called “black on white crime” on the Internet.

“The event that truly awakened me was the Trayvon Martin case,” the text says. “I kept hearing and seeing his name, and eventually I decided to look him up.”

The website and its contents, including who wrote the manifesto and when, have not been authenticated by investigators as of Saturday morning. The website appears to have launched in February of this year, but surfaced on Twitter and other social media platforms Saturday.

“It was obvious that Zimmerman was in the right,” the text says, adding that the writer was transformed by the “pages upon pages of … brutal black on White murders” chronicled online.

“I have never been the same since that day,” the writer said.

“I was in disbelief. At this moment I realized that something was very wrong. How could the news be blowing up the Trayvon Martin case while hundreds of these black on White murders got ignored?”

Near the end of the 2,000-word screed, the writer hints at why Charleston was targeted.

“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. 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 website is called “The Last Rhodesian.” In an image tweeted by South Carolina authorities this week, Roof is seen wearing a jacket with the flags of apartheid-era South Africa and nearby Rhodesia, a former British colony that a white minority ruled until it became independent in 1980 and changed its name to Zimbabwe.

Images on the website seen below, include a .45-caliber Glock pistol; a man who appears to be Roof taking aim with the gun; the same man posing in front of a sign that says, “Sacred burial site. Our African ancestors” as well as outside South Carolina’s Museum and Library of Confederate History; and the man standing on and burning an American flag.

“Living in the South, almost every White person has a small amount of racial awareness, simply beause (sic) of the numbers of negroes in this part of the country,” the text says. “But it is a superficial awareness. Growing up, in school, the White and black kids would make racial jokes toward each other, but all they were were jokes.”

It continues, “Me and White friends would sometimes would (sic) watch things that would make us think that ‘blacks were the real racists’ and other elementary thoughts like this, but there was no real understanding behind it.”
