Interesting thread that you started.....however, I must make some observations as well. You said, "And perhaps comment on the seeming contradiction between “gay travel” and the social integration that many gay and humanitarian activists seek." Usually "gay travel" indicates that someone is looking for information on gay life in the city where they are traveling to. Why post in a gay travel forum if you are not looking for gay bars, hotels, etc.? You could post the questions about Singapore in the Singapore forum. If you have a question about where are the gay bars in Singapore, the Gay Travel forum would be the place to post.
This is just my two cents......
