What’s so hard, benignuman?
There are many different aspects to the gay marraige issue:
1) Should states be allowed to sanction gay marriage?
No.
2) Should states be allowed to prohibit gay marriage?
Yes, it should be prohibited.
3) Should states be allowed to prohibit sodomy?
Yes it should be prohibited, and it was in some states until recently when the same court that invented a “constitutional right” to abortion overturned it.
4) Should states saction gay marriage?
No.
5) Should states prohibit gay marriage?
Yes.
6) Do the answers to 4 & 5 change if the states are prohibited, by the federal government, from prohibiting sodomy?
Irrelevant as sodomy should be prohibited.
7) Should Torah Observant Jews care one or another what the states do on this issue?
Yes. The Gemora in Meseches Chullin Daf Tzaddik Beis Amud Beis right at the top of the Amud states that one of the “Zchusim” that the umos hoilam have is that they do not write marital contracts for “mishkav zochur” and the Gemora says the reason the gentiles weren’t destroyed is because they don’t write marriage contract to mishcav zochorniks. And the act itself is a violation of the Sheva Mitzvos and we are enjoined to enforce the Sheva Mitzvos.
