The simple fact is that the purpose of marriage (from a secular society’s point of view) is to try to provide stable upbringing for the next generation of citizens.
Gays can’t produce the next generation of citizens, not without assistance from surrogates and doctors, or by adopting children, and so most of them will always be childless. Because of this, they have no need to be in stable relationships, because children are not an unavoidable result of gay couplings.
Now, just because they might be able to obtain children, gays will argue they should be able to get married in order to provide a stable home for the child. However, if they really cared about the children, they wouldn’t try so hard to obtain them when they knew they couldn’t provide that stable home in the first place, so we can see their stated motivations are a false veneer.
Whoever wrote this article needs to take several long refresher courses in English, public speaking, journalism & how not to sound like a moron when you are trying to make an argument. The last thing our side needs is someone attempting to make serious, educated arguments on moral issues and failing to convince others because he sounds like a moron. Harsh but nevertheless true ;)
