Parasites

"[The Jew] is and remains the eternal parasite, a parasite that spreads more and more like a harmful bacillus, as well as inviting only a favourable culture medium. The effect of its existence, however, is similar to that of parasites: where it occurs, the host people die after a shorter or longer time."

— Adolf Hitler, Mein Kampf

The use of the word "parasite" is not a coincidence.
