I think it is obvious that homosexuality is not going away. I think it is equally obvious that homosexuals will not stop having sex; men having sex with men and women having sex with women. At the same time, I do not see any benefit to society coming from men and women having illicit sex with those of the same gender. In fact, I believe that illicit sex among homosexuals can only harm our society. Likewise, I believe that illicit sex among heterosexuals can only harm society.
Given those presumptions, I wonder if society can benefit at all from gay marriage.
For example, is it reasonable to assume that an increase in same-gender marriages can result in a decrease in sexually-transmitted disease among the homosexual population?
Is it reasonable to assume that an increase in same-gender marriages can result in a decrease of broken homes (via gay spouses leaving the heterosexual spouses they married despite knowing they were homosexual because they thought marriage would cure them or because they wanted children)?
Is it reasonable to assume that an increase in same-gender marriages can result in a decrease in illicit sex, thus improving the moral fibre of our society?
Certainly there must be other such positions one could make where same-gender marriages might improve our current society. Are they all reasonable? Are any reasonable? Is society better off if homosexuals are denied same-gender marriage?
