Agreed, but there is nothing granting the power to limit the rights of gays either
Gays don't have special rights because they cannot legally be a class of people. There's nothing enumerated in the Constitution giving special protections to anyone based on their aberrant behaviors. The only behaviors I know of specified for protection under the US Constitution are the right to bear arms and the right to practice one's faith. Ass sex, bulimia, drug addiction...none of them are mentioned in the Constitution. There is no such legal thing as "gays". There are only people across all races and both genders doing aberrant things with their hoo-hoos. That does not make a special class of people.
The 7th circuit federal court of appeals just echoed those sentiments. They said this year that homosexuals or sexual orientation (behavior) is not covered under the 1964 Civil Rights Act. That's a very gentle way of saying they are also not covered under any measurable stretch of the wording of the US Constitution, nor under any whisper of intent within it from the Founding Fathers; or Congress since then. Congress is the only entity who may amend the Constitution and so far there's nothing there about homosexuals or marriage..
The USSC will tell you Obergefell was about same-sex marriage, not "gay" marriage. And that is because if they said it was about "gay" marriage, they'd run into all the legal snags I just mentioned. However, making "same-sex" marriage legal, stripped children of either a mother or father for life via a new contractual term....to their proximate detriment. And that isn't allowed to be done under the Infancy Doctrine. So, any state may legally choose to do anything they like on marrying "gays" or "same-sex" people, in the interest of protecting children; since Obergefell is not a legal Ruling.
States not only CAN deny same-sex marriage on behalf of children...
federal law compels them to always default in favor of children when a harm to them is perceived. Legally removing even the hope of a mother or father for life from a child as a contractual term is a direct harm to that child's mind and person.
