This guy Yong Wen San, who commented on Quora, is a highly educated guy. I walked away from his questions on Quora simply because I did not want to embarrass him but he insists on continuing and I thought it best to answer him. I have high respect for him.
The problem for many of us is that we quite often wear blinkers and do
not want to see different perspectives. (Different perspective is the motto for
my blog which was suggested by one of my sons.)
