I am fully in support of gay marriage and I will be quite happy if Taiwan becomes the first country in East Asia to allow it. Given that many parts of the U.S., still prohibit gay marriage (and even its federal status s not entirely coequal with straight marriage), I think Taiwanese can be rightly proud that they have managed to push this issue so far already (even my home state of California only allowed it in the last couple of years). Unfortunately, though it appears that this bill is going to be stalled in the LY. taipeitimes.com/News/front/a ... 2003607386
I've listened to many arguments from the Religious Right I the US about how gay marriage will "undermine the family." And while there is sometimes reference to "Judeo-Christian" values my sense is that most serious anti-gay marriage groups try not to base their arguments solely on the idea that "the Bible forbids it." Of course, my personal view is that most anti gay marriage folks in the US are motivated but religious intolerance and bigotry irrespective of what they say.
In my own Taiwanese family and circle of friends in the US, the vast majority of people seem to be in favor of gay marriage. I have gay relatives and friends who grew up here; they were very worried about parental nonacceptance on "coming out." In one case it ultimately went very well, where the parents were extremely accepting and have incorporated his long term partner into the family. In the other case, it was a little rockier. The parents say they "accept" it, but they don't want to ever talk about it and have asked those of us who know to refrain from mentioning it (or her partner) in public.
For those of you familiar with the Taiwanese American (and perhaps the greater Asian American) community, you may be aware that there is a definite streak of evangelical Christianity. I think the combination of some aspect of Christianity and Confucianism form the basis of the opposition some have to gay marriage, but I wouldn't solely attribute such views to either source.
