I agree with the idea that the religious argument isn’t the best argument and if anything retreating to that argument has been used to box the issue in. However Bill who is supposed to be a conservative Catholic is being intellectually dishonest because there are plenty of secular non religious arguments the problem is who does he bring on his show to talk about SSM? Does he bring a PhD who makes a secular and even scientific argument against it? No he doesn’t he and “conservative” media almost unilaterally call on religious representatives or political activists. So who has made it seem as if the only argument is a religious argument? It has been Bill and others. I believe that there are several strong arguments to be made.
1. The liberty argument. Homosexual activists are one of the most relentless users of political correctness and thought police methods. This is a clear winner for SSM opponents and there are hundreds of examples of how SSM has been used to discriminate against and suppress anyone who even causally disagrees with gay propaganda on the issue. The problem is conservative media fails to make the over arching case. While the left makes a gay student going to the Prom a national issue our conservative media can’t seem to find time to whip up the fervor when a student is kicked out of a college program because of disapproval of homosexuality/SSM. Every time a person is fired or discriminated because of views running contrary to gay activism they should be highlighted and given national attention as examples of how gay activism/SSM threatens liberty.
2. Show gay activists for what they are. We have allowed two faces of gay activism to exist. One for public consumption and the real one that is filled with sexual exhibitionism, obscenity, and vulgarity. The later would never be accepted by the mainstream but because the media doesn’t dare show or even discuss the reality of gay pride and gay activism people most of whom do not wish to expose themselves to such things end up thinking gay activism is about “equal marriage” and innocuous. Shouldn’t homosexuals be held to the same standards of decency as straights? I’ve never seen the degree of depravity in parades and in events as is typically on display at gay related activities.
3. The biological argument. Homosexuality is at its core damaging to the human organism’s ability to reproduce which from a pure Darwinian perspective is the definition of unfitness. This angle I believe hasn’t been used as effectively as it could against the left in general to provide a wedge. A lot of young people have been led to falsely believe that opposition to SSM and homosexuality is just a product of religion much as Feminists pushed the idea that the differences between men and women were just products of environment and “the patriarchy”. The reluctance to point out how homosexuality runs contrary to evolution I believe is rooted in that many especially religious opponents are afraid of using the tools of their foes against them plus many are afraid of the implications to their own views on reproduction because many religious people live essentially lives that could’ve just as easily been defined by Planned Parenthood minus abortion.
That said the religious argument shouldn’t be ignored because religious liberty faces a dire threat because SSM is really a tool to co-opt and control religious primarily Christian groups. Its a way to define Christianity as bigotry and anyone who thinks this is just the worry of “Bible Thumpers” is an idiot because government suppressing/control of religion and family is the key to establishing what is an essentially centralized secular state religion which will threaten liberty for all.
The history of the church has been clear on sexual immorality and has pointed out the evils pedophilia, adultery, homosexuality. It's society that keeps flip flopping on the issue.
