The manifesto, reviewed by Insider, details a deep-set hatred of nonwhites.

The man calls for the people of a large number of North African, Asian, and Middle Eastern countries to be "completely destroyed" on the baseless idea that they are biologically inferior.

The author, who wrote in German, also claimed Trump stole some of his ideas.

"A billionaire in the USA is implementing my policy recommendation (even some slogans I developed like 'America First, Buy American and Hire American')," the manifesto says.

The author also criticized other "races and cultures" as "destructive," singling out Islam.

Nothing really intelligent to say about these nonsensical racially motivated attacks besides RIP to the victims

good to see it is mobilizing people for a greater good

Nice to know you compare everyone who disagrees with you to this guy.

RIP

Should’ve sued trump for stealing his ideas instead of shooting people
