... he ruled that "the classification imposed by the marriage laws based on sexual orientation is not substantially related to an important governmental interest" and is therefore unconstitutional.
Well, we knew that. So is it?
The issue will have to come before the US Supreme Court, unless it ducks it.
In preparation for that, it is necessary that all of the reasons and backup for those reasons (evidence) be compiled. Naturally, "scientific" research studies and reports will be utilized.
What are the methodological issues with the research on both sides of the issue? It will be necessary to anticipate the criticisms and be ready with the best rebuttals.
It will be important to raise much more than simply "'promotion of procreation ... child rearing and the well-being of children ... tradition' and business concerns." The actual mental ill-health that is the condition called homosexuality must be readdressed in full.
It is never a healthy mental state. Heterosexuals can have mental problems too, but unlike homosexuality, heterosexuality, per se, is not inherently disordered.
The arguments that homosexuality is genetic are extremely weak and should not stand up in court. The argument that it is epigenetically based cuts both ways, which opens the door to the fluidity-of-sexuality point: that "orientation" is subject to change, which it clearly is and which it is recognized as being by both the American Psychological and American Psychiatric associations.
Of course, the US Supreme Court is a secular body. The US Constitution is a secular, not sacred, document. The United States is not, and never has been, a Christian (or Judeo-Christian) nation. There have obviously been many people who've claimed to be Christians living and voting within it, but a truly Christian nation would be a theocracy, which the US has never been, quite the opposite.
I mention these things because true Christians should know that the laws of the United States are not, repeat, are not The Law. For Christians, no matter what the secular and Godless government does or says, marriage can never be between two or more females or two or more males.
Therefore, Holy Matrimony and secular marriage are two different things. Those who are lawfully wedded under the secular government are not necessarily lawfully wedded under the true Christian religion.
I do not, nor will I, recognize any homosexual marriage as being the same marriage meant by Jesus Christ:
But from the beginning of the creation God made them male and female. For this cause shall a man leave his father and mother, and cleave to his wife; And they twain shall be one flesh: so then they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder. (Mark 10:6-9 KJV)
That "one flesh" is the one and only condition of Holy Matrimony recognized in the true Christian religion and for excellent reasons, all of which argue against the utterly misguided, reported "federal or state judges [who] have knocked down bans on same-sex marriage" in 19 states now.
The problem is ancient, but the "modern" problem began with the US Supreme Court's completely evil decision in Lawrence v. Texas, wherein that court ruled that the state had no compelling reasons to outlaw sodomy.
Contrary to that court's sloppy reasoning, sodomy is a fundamental error fraught with untold negative personal-health and societal consequences.
There are deceptive and/or ignorant homosexual and pro-homosexuality propagandists who argue otherwise, and there are those who say that not all homosexual males practice sodomy and that many heterosexuals do practice it.
I won't give the laundry list of reason sodomy is unhealthy, but the idea that not all homosexuals practice it is irrelevant, as the exceptions make the rule in this case. Also, that many heterosexuals practice it doesn't render it healthy. It also simply is not relevant.
The fact is that if the US Supreme Court had ruled correctly that the State of Texas had a compelling governmental reason for banning sodomy (health reasons, as suggested above), the issue of homosexual marriage would not be before us as it is.

Unfortunately, this is one of those issues where only the negative results of the direction taken by the government will change people's minds. It will unfortunately take time for the negatives to mound up and become glaringly obvious. It is unfortunate because there will be many casualties along the road caused by the myopic, inferior reasoning of the entire pro-homosexuality culture.
