Ok, I hope we can agree on the following premises:
A. Societies, including ours, do legislate morality.
B. That is ok, as long as it is a true measure of the morality of the nation.
C. Subject to constitutional restrictions.
D. Our society finds homosexuality immoral.
E. Our society finds homosexual marriage immoral.
F. Our society sees a benefit in not allowing homosexual marriage.
G. Homosexual marriage is not per se assur, since it does not exist. Neither is incestuous marriage per se assur.
H. Men making other contracts is not immoral or assur.
Now, I think we disagree on:
A. Is homosexuality really immoral.
B. Is homosexual marriage really immoral.
C. Are things which are not per se assur against the ratzon hashem.
We probably also disagree on whether the US constitution bars bans on homosexual marriage. However, I have little interest in discussing this. I don’t believe either of us have the necessary knowledge to carry on a proper conversation on the issue. (You are an engineer, correct?)
