I think most people are shocked at the unions of Western men and Asian women as the girls are young enough to be their grandchildren, it makes the man look like a pervert!  Plus I am told many of the men leave these women as some are already married at home.  I knew one English man and he married a Chinese prostitute, he bought her a home in China and when he became ill she came to see what she could take from him.  Maybe the men deserve these women!
