Don't have to because the sillies above in the thread flatly state there isn't. It's their obligation to show by objective evidence. If there is not any such, then the problem is relative, and the far social con right has clearly shown they have no objective argument for denying marriage equality.
When their puffed up pretend intelligentsia pops up out of the box and spew their nonsense, it is time to pass coffee and donuts and enjoy the burlesque.

one piece of information that never materialized from the Human Genome Project was the identification of the so-called gay gene. There is none, Homosexuality is not truly a genetic issue, but as Freud and Socarides theorized - it's a Mental disorder.

I find it hard to take anything seriously from a site that considers evolution a myth
Here's some stuff for thought:

A gay Gene - Is Homosexuality Inherited Assault On Gay America FRONTLINE PBS
Most scientists seem to think that homosexuality is a combination of genetics (likely not one gene), enviroment, and biology. It's hard to untangle causes but they're pretty much in agreement that it's hard-wired, not a mental disorder.

Okay - so what has that to do with what I posted ?
I don't always you agree with what you post - in fact some of your stuff is off the wall - does that mean you lose ALL credibility. The article YOU linked to is not the article I linked to - if you can't refute the content and they are presenting valid evidence who cares what their other opinions are ?
And just for the record - I'm not a Christian and have written against Christianity on an independent blog I maintain - so don't even try the Bible thumper argument .
What has to do with what you posted is the articles I linked to after the comment. I haven't called you a bible thumper - but sources matter and when you choose a bad one, it can come back to smack you.
Most of what that article is saying is that there is no "gay gene" -- but that is not what the scientists are claiming. What studies have been done seem to show some genetic influence on sexual orientation and genetic influences are not always simple dominant/recessive modes of inheritance. For example some traits may only show up or become activiated under certain environmental influences (piglets show one phenotype when they are kept in domestic conditions, but if they become feral, other genes switch on and change the phenotype quite drastically).
Your source is picking apart studies largely by focusing on searching for "a gay gene". It also takes a critical look at "ex-gay" type therapies. The conclusion it draws from those are that some - a very tiny proportion - of self selected gays can change their orientation for at least 5 years and it attempts to use that to imply it's malleable.
Robert Spitzer conducted a study on 200 self-selected individuals (143 males, 57 females) in an effort to see if participants could change their sexual orientation from homosexual to heterosexual (2003, 32:403-417). He reported some minimal change from homosexual to heterosexual orientation that lasted at least five years (p. 403). Spitzer observed:
The majority of participants gave reports of change from a predominantly or exclusively homosexual orientation before therapy to a predominantly or exclusively heterosexual orientation in the past year (p. 403).
In summarizing his findings, Spitzer declared: “Thus, there is evidence that change in sexual orientation following some form of reparative therapy does occur in some gay men and lesbians.” He thus concluded: “This study provides evidence that some gay men and lesbians are able to also change the core features of sexual orientation” (p. 415).
However, that study has been widely politicized and misrepresented:
Spitzer s Apology Changes Ex-Gay Debate NPR
Dr. Robert Spitzer's research was widely cited by those who conduct conversion therapy as proof that it worked. Dr. Spitzer says his findings were misinterpreted, and apologized. The American Psychological Association has said there is no evidence that it's possible to change sexual orientation.
Can some gay people change their orientation? Apparently. But it's also likely that homosexuality overlaps with bisexuality and people who self-identify as homosexual are in reality bisexual.
