Sorry, you are not the only one who knows biology.
What is about 5% of those from biological reasons for being gays (those are the gays that I respect. Of course, no one, even themselves sometimes, know what is real. So it's better to respect them all but not emphasize and encourage it.) has been enlarged by all the irresposible behaviors to make it looks like the base is over 30%. I am worried about the next and next, next generations. It's for sure that we are going to have more and more "gays" in the generations to come if we continue to emphasize it. Those are not the gays from biological reasons, but from confusion and twist of emotions, from disappointments and rejects by the other sex, from the educations in the growing up period.... I truly believe that there are a large number of gays who are not biological gays. You know what? The natural reproductive process will be less and less in this way, and that is against nature which I am talking about.
And "to mind your own business" sort of thinking about it is an irresposible way about the moral issues, which is similar to deregulation in the financial system.
I stated my true believes and thinkings, like you all having been doing. If my way has offended you all, I am sorry.
