So basically you resign?
A behaviour isn't part of your identify unless you choose to make it so.
And it is unnatural (and sinful, but thats a different matter), that much is clear, doesn't mean that you can't do it, or should be stopped if you want to, thats your prerogative. Yes it does hurt people, but the risks are something that you should be taking into account. Gay marriage and gay adoption however hurts soceity, and thats where I have to say no.
But its doesn't aim to exclude homosexuals specifically.
It is a blanket exclusion of ANY and EVERY relationship that isn't one (unrelated) man - one woman. This is a totally fair standard, as I have established, and it is one which has been set not only by our society throughout its history but by almost every single other.
Marriage should not be defined in terms of love, and has never been so. If you define it by love, what is there preventing two children from marrying, a man and an animal, three people, four people, people who are directly related? etc. If gays are allowed to marry because of love alone, then why should any of these be excluded as well?
We both agree that marriage is something special and means something very specific. The only difference is that I know what its definition is while you know it means something specific but have no clue on what exactly that something is.
To demonstrate the insensibility of sanctioning same-sex unions as "marriage" consider the following point made by Francis Beckwith: Just because you can eat an ashtray doesn't make it food. Food is not determined by what you put in your mouth, but by the nature of the substance itself, and the types of things the body is designed to consume and use. Just because two homosexuals pledge the vows of marriage does not make it a marriage. Marriage is something in particular. Homosexuality is not congruent with the nature and purpose of marriage, and therefore we should not call same-sex relationships "marriage," nor give homosexuals the same rights/benefits we give to heterosexual unions.
No, what I actually want is for you to come to your senses and realise that, Bible aside, there is no credible reason at all why homosexuality should be tolerated let alone encouraged in society as being equal in any way to heterosexuality, why it should be considered natural when it clearly isn't, why it should be considered a healthy and valid alternative when it clearly isn't and that there are no reasons whatsoever as to why gay marriage or gay adoption should be permitted.
I realise tha without Christ you have little hope if any of abstaining from the sinful desires which presently rule your life, both sexual and non-sexual in nature. This is why my arguements against gay marriage and gay adoption, and that homosexual sex is unhealthy and unnatural (as I hope you noticed) have little religious references within them.
Lame song, what about Thousand Foot Krutch's, "Faith, Love and Happiness" (If you like Skillet Seck, you'll love these guys)
'Cause everyone is falling away
Feel like they're stolen from me
Wish everything didn't happen to me
All I want is faith, love and happiness
Everytime one runs away
Another one's returning
Wish everyone could just see your face
Faith, love and happiness
