My remark was intended as a joke, but England was perhaps enticing to  him 
because of its lack of ethnic diversity at that time.

Well, we do know that is not why he left America.  He was in Germany  as a 
student when WWI broke out and managed to make it to London.  He  settled 
in, got married, and did not want to be a philophy professor in the US  but a 
poet in England.  His parents did not want him to be a poet, so he  stayed 
away.  Of course that is only one thread of a complicated set of  potential 
reasons, but I know of no suggestion in his early texts that he  wanted to be 
in a homogeneous environment and that was his motive.

shock today to witness the cultures existing in London.

The sentence that precedes the one about "free-thinking Jews" is as  
follows:  The population should be homogeneous; where two or more  cultures exist 
in the same place they are likely either to be fiercely  self-conscious or 
both to become adulterate."
