Hi, Doc.

Got some possible answers to your question.
1. Some people might conclude that you'll find a way to link overseas money/"dirty" money/Asians to almost ANY subject you care to comment about. 

2. Nor is the person possibly responsible for blocking your post necessarily "some power-hungry ideologue. " 

3. The reason for the action may not be fear of "speech", Doctor.  Nor perhaps a reader's "delicate political preferences."  It may simply be that somebody is irritated and impatient by your continual linkage to what, in decades past, was politely referred to as the "Oriental problem."  

Who knows how many others this reader represents?  Take the hint.
