'Muslim' is just a word...
...and here in the West we have come to stereotype people of that faith and ethnicity, espcially so since 9/11. We project our Western beliefs and understanding without taking into account that muslim and other societies are just as complex as our own. Non-western societies by and large also have histories of alternative sexual cultures and practices.
Based on what few studies have been done on this topic, it would appear that Western influences, through colonization and the export of our social, moral and political ideologies, has had a significant influence on the sexual morality of other cultures over the years.
A good point in case is Papua New Guinea. A nation with many different tribal groups that, in comparison to many other countries, was spared much contact with Western values until relatively recent. A number of studies have found that homosexuality, which once was widely practiced and fully accepted amongst the different tribes, has become stigmatized. Many tribal groups practiced ritualized homosexuality as a coming of age rite of passage for adolescent boys. Once boys came of age they were expected to take a wife and sire children, though there were no cultural restrictions regarding homosexual relationships. Apparently these practices were deeply entrenched amongst many tribal groups as recently as twenty years ago. Twenty years on, with more tribal people moving closer to towns and adopting western ways in their search for money, material goods, medical help and education, they are also finding our value systems and morality. Thus, atttitudes towards homosexuality, particularly amongst younger papuans, have become very negative. Male homosexuality is illegal in Papua New Guinea.
The concept of what we consider masculin and feminine in the West is also very different in many parts of the world. Asian societies have, by and large, always been far less condemning of homosexuality and gender-bending. Chinese society only became prudish as a result of communism - a western ideolgy. Much of the middle east is still strongly influenced by its British and French colonial history.
Here in the West we have created a homosexual culture, which, to my way of thinking, is contrived and restrictive in its own peculiar way. How we define ourselves and who we are supposed to be is currently crammed into this little three letter word that is applied to one and all with 'gay' abandon. For necessity and survival we have turned our sexuality into a ghetto culture that, in itself, is very restrictive and fosters its own prejudices. I hope that, when the time comes (very soon), we can move beyond the gay ghetto and it's stereotypes. Just as it is important to assert our rights, it is equally important that we don't end up marginalizing ourselves in the process.
Anyway, I've attached a link that some may find interesting.
