而且同性恋是不能选择的啊，就是肤色一样。

    这个怎么理解？好像同性恋也有后天形成的吧？著名电影蓝宇中的主人公不就是一个？

我觉得美国心理学会(American Psychological Association)网站上的观点比较客观。

What causes a person to have a particular sexual orientation?

There is no consensus among scientists about the exact reasons that an individual develops a heterosexual, bisexual, gay or lesbian orientation. Although much research has examined the possible genetic, hormonal, developmental, social and cultural influences on sexual orientation, no findings have emerged that permit scientists to conclude that sexual orientation is determined by any particular factor or factors. Many think that nature and nurture both play complex roles; most people experience little or no sense of choice about their sexual orientation.
