Again, homosexuals will continue to homosexuals, meaning have sex with homosexuals. Studies show homosexuality, in thought, cannot be converted to heterosexuality. A slew of psychology studies demonstrate that gay parents do not yield more gay children. So this argument that you don't want more homosexuals in the world doesn't make sense. How would denying marriage and adoption abilities increase homosexuality? The rest of your poorly constructed argument rests upon this point.
You haven't demonstrated how this policy change in marriage and adoption would increase the homosexual population.
Therefore, with the homosexual population as it stands, why not make choices that improve the
millions of other point of morality, again, as dictated by conventional and long-withstanding institutions?
Improving the lives of homosexuals and heterosexuals alike.
Your proposition, as I explained earlier, harms all groups, homosexual or not, in a variety of systemic ways. That is greater sin if we are to attempt to quantify:
Same number of homosexuals having sex (list of negative consequences I listed in the other post)
< Same number of homosexuals having sex, developing long term relationships, adopting children (abused/beaten/neglected in the Foster Care System), improve relations between religious/nonreligious groups, decrease polarization of politics, ect.
One stance promotes immorality by focusing on one unchangeable factor.
Oh, and a fun fact sheet of Foster Care outcomes, well just a few of them:
Well, have fun arguing:
Foster Care > Homosexual Adoptive Parents (high standards of medical, criminal, financial screening)
Also, we don't have free will for our race, religion, thought processes, anything. We have inherit qualities that interact with an environment. In fact, most people don't choose to not be a christian. We inherit social convention, laws, and customs of our society and operate by those conventions, including religious beliefs. How, for instance, is a Chinese citizen choosing not be a Christian? They have not reified Christian doctrine passed down by parents, and further, they are likely to have been taught Christianity is wrong. So, no one, operates under the control of their own "free will" whether we are talking psychopaths, Christians, homosexuals, heterosexuals, ect, in the choices we make. Social structure and customs, taking into account the natural qualities possessed by a variety of people, is how choices and behaviors develop. We should make policy changes based on this knowledge to improve relationships between genetic qualities (homosexuality) and legal statutes/conventions.
