It still is a state issue. Why don't you point out a part in the Constitution where the Federal Government has a say of who can be married and who can't. Let me say it for you. You can't, hence it cannot be debated. It IS still a state issue, like it was before. Before, if you wanted to get married, you went to another state where it was legal. Now you have no choice. And this is supposed to be a free country. Really?
Any powers that are not part of the Federal Government is up to the states. Free speech is federal thing, not a state thing, so every state must agree with it to be apart of the union. However gay marriage is not in one of the federal governments powers. Hence it is a state issue. But the Supreme Court says "Nuh uh, we're gonna make it legal everywhere whether you like it or not.
I'm telling you, this is a seriously bad sign and you'll all regret being in favor of something like this.
You appear to have a very poor grasp of the Constitution, Rule of Law, and what was decided in this case. Marriage is still a state issue--states have purview over such things as granting marriage licenses--except when the conflicts between the ways that the different states handle marriage cause problems for the citizens. Then, the SC has the responsibility of hearing and ruling on the case. In the prior post, I explained the CONSTITUTIONAL reasons it was before the federal SC.
Chief Justice Roberts could have refused to have the court hear the case, as the Chief Justice does with literally thousands of cases every year. Obviously, last fall he thought there was a legitimate reason for the court to hear the case, otherwise he would have said no. The court heard the arguments of the two sides, and entertained briefs from many "friends of the court" on both sides. The justices then deliberated, and the decision could have gone either way. Had the majority ruled the other way, you would presently be trumpeting how wonderful and wise the SC is, how the system WORKED, and so on. However, the majority were not convinced by the arguments that you prefer, although Roberts did an apparently good job of laying out the reasoning. Instead, the majority were convinced by the argument that there is no compelling governmental reason for states to discriminate against GLBTQ individuals, and the patchwork of policies by the different states needed to be resolved. You may not like it, but it is NOT the end of the world, or even the public debate about the topic. Some like to say the SC is the final word, but it's not.
So what happens next? State legislatures can try to draft new legislation, and Congress can do so as well. Any such legislation would have to have executive approval, then if passed would undoubtedly face another court challenge, that might well in a few years result in ANOTHER SC case--which could go either way, depending on the language of the law, the intent, the legal arguments, the sitting justices, etc. To stand Constitutional muster before the court, the legislation would have to clearly establish a compelling governmental reason in favor of discrimination.
Also, Constitutional amendments can be proposed in Congress to declare marriage in the US to be only between one man and one woman. Any such legislation would also need to be approved by the procedures laid out in the Constitution, but it could happen. If it did, then that would become the law of the land, and the current court ruling would become moot.
My guess is that people who oppose same-sex marriage will push for new legislation of various sorts and work to make sure that only conservatives get elected to office, get appointed to the bench and the SC, etc. And people who support marriage equality will continue to oppose and challenge those efforts. After all, that's what's been happening regarding people's rights based on gender, race, skin color, ethnic or national origins, age, handicapping condition, etc., etc., etc., for more than 50 years.
