Two things are especially worthy of note in this article.
First it says "the fact that the leaders of Bolshevism belong to the Semitic race". Not "are believed to belong to", "are wrongly thought to belong to", "are alleged to belong to". Just "belong to".
Second, it is fascinating that the strongest early supporters of Zionism were the "violent anti-Semites". This contradicts Jewish propaganda in the present day, according to which critics of Israel are antisemites. On the contrary, many antisemites have traditionally seen Israel as the Final Solution to the Jewish problem. If the grievance-mongering diaspora would live like a normal people in its own land, many of the causes of our current discontent would disappear.
This is why Hitler at first supported the Zionists in Germany (see here and here), as Ken Livingstone correctly claimed, before facing persecution from Jews who would prefer that we "Never Remember" that part of history.
