Coincidence? I think not.
In Taiwan 30 years ago--before our grand U.S. cultural "nonsensibilities" had smothered some of their sensibilities, very heterosexual men would walk down the street hand in hand, maybe arm in arm.
At least 14 years ago, even more of the same was standard in Mainland China. It was common for men of all ages to be affectionate. . . whether on the street, at a concert, sports meet, wherever. . . and they were NOT gay.
I was told such was especially more common after the Cultural Revolution.
I was brave enough to "do as the Chinese in China" and found relationships could be much more quickly closer, more authentic, more communicative, caring etc.
I've always had a curiosity that I've never seen any research on and suspect if there is any that it's highly classified in such countries. We know that fathers (contrary to conventional assumptions) who are NOT affectionate produce more homosexual sons and those who ARE AFFECTIONATE produce, as a group, far fewer homosexual sons.
So I've always wondered, if homosexuality went up when U.S. cultural "nonsensitivities" flooded such a country. If anyone has any data on such, I'd be interested.
It has also often amused me that Christian men are often supposedly eager to obey the Bible except when it comes to "greet the brethren with a HOLY kiss."
