There are two interesting stories in recent issues of Chinese newspapers that highlights the gap between Chinese cultural attitudes and the west in relation to this topic.
But first I should point out that gay relationships are problematised in different ways in China and the west.
In the west the problem arises because of the moral barrier erected by Christianity. Pre and non-Christian Graeco-Roman culture were not deeply against men having sex with other men. There was a stigma attached to men who took a passive role in a sexual activity, but how deep that stigma ran is difficult to figure out. The subject often becomes controversial when the personal views of a scholar run counter to the material he is considering. If anyone wants to consider Graeco-Roman attitudes to male to male sexuality the Wikipedia entry under Homosexuality in Ancient Rome ( http://en.wikipedia.org/wiki/Homosexuality_in_ancient_Rome ) could be a good place to start, but I suggest that it should not be the end of anyone's search for understanding. But the coming of Christianity brought a change in attitudes, that continues to this day and results in enormous tensions for some people and often a recourse to violence because of internalised homophobia. Because of the controlling nature of Christianity same sex activity was often criminalised, and only recently has there been a de-criminalisation process, resulting in same sex attracted people being able to live more honest lives. Part of the de-criminalisation has been the legalisation of same sex relationships through gay unions or marriage.
In China, prejudice has an entirely different foundation, part of the contemporary prejudice is based on Confucian family traditions that place a responsibility on family members to reproduce, but in addition there has also been some absorption of contemporary western prejudice absorbed during the modernisation process. This is a fairly recent devlopment for as late as the 1920's it is reported that there were many blocks of male brothels to be found in the centre of Beijing.
This preamble is leading up to two recent news items in a Chinese newspaper and the reactions to it.
