I didn't know that he was antisemitic... wow... hmm
He was a deformed jew, who thought the jewish "problem" in europe is going to disappear if simply there wont be any jews!
they will all become Christians and give up the inferior culture they had called Judaism.
Thats what he thought, that judaism is inferior. He hated judaism.
The only good thing he did in his life is searching for a jewish country, after he understood that nobody will never accept the jews in anywhere they go,
but again, he failed to achieve Israel so he thought that the jewish land will better be Uganda.
