Opponents of gay marriage have a million reasons. Here are the most common ones and why they don't hold true at all.
LGBT advocates fear Kavanaugh’s votes on gay-rights issues
Marriage is an institution between one man and one woman. Well, that's the most often heard argument, one even codified in a recently passed U.S. federal law. Yet it is easily the weakest. Who says who marriage is to be defined by? The married? The marriable? Isn't that kind of like allowing a banker to decide who is going to own the money in stored in his vaults? It seems to me that if the straight community cannot show a compelling reason to deny the institution of marriage to gay people, it shouldn't be denied. And such simple, nebulous declarations are hardly a compelling reason. They're really more like an expression of prejudce than any kind of a real argument. The concept of not denying people their rights unless you can show a compelling reason to do so is the very basis of human rights.
Same-sex couples aren't the optimum environment in which to raise children. That's an interesting one, in light of who society does allow to get married and bring children into their marriage. Check it out: murderers, convicted felons of all sorts, even known child molesters are all allowed to freely marry and procreate, and do so every day, with hardly a second thought by these same critics. So if children are truly the priority here, why is this allowed? Why are the advocates of this argument not working to prohibit the above categories of people from raising children?
The fact is that many gay couples raise children, adopted and occasionally their own from failed attempts at heterosexual marriages. Lots and lots of scientific studieshave shown that the outcomes of the children raised in the homes of gay and lesbian couples are just as good as those of straight couples. The differences have been shown again and again to be insignificant. Psychologists tell us that what makes the difference is the love of the parents, not their gender. The studies are very clear about that. And gay people are as capable of loving children as fully as anyone else.
Gay relationships are immoral and violate the sacred institution of marriage. Says who? The Bible? Somehow, I always thought that freedom of religion implied the right to freedom from religion as well. The Bible has absolutely no standing in American law (and none other than the father of the American democracy, Thomas Jefferson, very proudly took credit for that fact), and because it doesn't, no one has the right to impose rules anyone else simply because of something they percieve to be mandated by the Bible. Not all world religions have a problem with homosexuality; many sects of Buddhism, for example, celebrate gay relationships freely and would like to have the authority to make them legal marriages. In that sense, their religious freedom is being infringed. If one believes in religious freedom, the recognition that opposition to gay marriage is based on religious arguments is reason enough to discount this argument.
