A whoever said that divorce deprives kids of a mom and dad.
What divorce does is provide them with a new chance at a new set of mom and dad that get along and don't cause them psychological harm. States grant divorce only reluctantly and they still seek to preserve the quasi- mom and dad atmosphere in custody arrangments until a new marriage happens with either or both of the old estranged parents.
For continuity...
Plenty of states to choose from.
But I pick: Supreme Court challenge and eventual knock out, for anti-same sex marriage/anti-gay legislation.
There's no such thing as "anti-gay" legislation in this question.
The states are preserving sovereignty on the privelege of marriage.
Yes, I said PRIVELEGE.
If it wasn't a privelege, anyone of any age, blood relation or number of people could "marry". I assume you object to 13 year olds marrying? Yet they are allowed to in New Hampshire. Would you want your state's ability to regulate marriage to not include 13 year olds forcibly removed by the fed? No, of course not.
Billy Bob and Irma Jean are brother and sister in the backwoods of Kentucky. They have three kids together. Would you define not allowing them to marry as abusive? No, of course not!
Over in Utah, there's a man who wants to marry 8 wives. Would you want the fed to tell your state to not make "anti-polygamy" laws?
So, we all agree that marriage is subject to regulation. And we all agree that homosexuality is one of those weird things like 13 year olds marrying or brother sister marriage. Or a man taking 8 wives. Only in the case of homosexuals, it's the only weird one where an institution would be created where sons are fatherless and daughters are motherless.
So laws that exclude homosexuals also exclude certain ages, certain blood relations and other deviant sex practitioners (polygamists). Even monosexuals who prefer to be alone. Should their kids also be denied the benefits of marriage? Why? Do you "hate" them?
Etc... No such thing as "anti-gay" laws. They are just laws. Just regulations that are not meant to single out any one of the many types of people who cannot be married in each respective sovereign state.
If you think gay marriage is such a great idea, then sell it to the People. Don't force it down their throats with your Biased-Supreme-Court piping bag. You tend to make political enemies that way. Doing so while grafting your cult onto the hip of the democratic party means that you are also alienating vital middle voters who don't believe in gay marriage. And even if they are ambivalent about gay marriage, certainly do not like to be told they don't have a say in the debate should it come to their state. Fatherless sons and motherless daughters is BIG DEAL to a LOT of people when they really start to think about it..
