Sil, LGBT marriage is a done deal. That's not going to change in your lifetime.
Unless an advocate for the main beneficiares of the marriage contract (children) comes forward and asks that Obergefell be reheard for these reasons
1. That one of the Justices had advertised to the public before the Hearing how she was going to vote on it: undermining the American judicial process, creating a mistrial (
Capteron v A.T Massey Coal 2009) and
2. That that same Justice and one other were performing gay marriages as federal court Justices while the question of "should the fed preside over the states on the question of gay marriage being legitimate" was pending to be Heard (again,
Caperton v A.T. Massey Coal 2009) and
3. That there isn't even a remote insinuation in the US Constitution that homosexual behaviors have special rights while other sexual behaviors like polyamory do not (somehow; ironically citing the 14th Amendment).
Hively v Ivy Tech (7th circuit 2016) found that homosexuality is NOT covered under the 1964 Civil Rights Act even. and
4. That "gay marriage" uses a contract to dismiss even the hope of children (the main beneficiaries of the marriage contract) having the missing gendered parent (which may vitally be their own gender as a role model) missing from a "married" home..which is forbidden under the
Infancy Doctrine, children, and contracts.
So, you may be quite wrong about that. The first priority the GOP has in the coming weeks is to fill lower federal court appointments with conservative judges; and to fill the vacancy on the USSC with a conservative Justice like Scalia. When Ginsburg either steps down or is impeached (see #s 1 & 2 above), they will replace her also with a conservative. Then your mistrial called "Obergefell" will be reheard; for the sake of the children it hurts if for no other reason..
Marriage was invented over 1,000 years ago to REMEDY the situation of a child not having either a vital mother or father....not to legally create an inescapable situation where the child will NEVER have a mother or father!
