Here all along I thought people were born of free will....it's a dangerous path to start to blame genetics for every deviant behavior there is, besides it just ain't so.
From what I've read, this is much more true for gay men than lesbians. For example, see "The Man Who Would Be Queen" by J. Michael Bailey.
Did he think they were capable of feeling love in the way that he felt love for his children and his wife. He said they did.
This is tricky. There was an old psychiatric cliche to the effect that homosexual men had a problem with intimacy, period, while lesbians had a problem with intimacy with men. These ideas are hopelessly unacceptable in today's PC world, but I suspect that there was something to this.
Ben Bagley, the late, and gay, producer of wonderful record albums of forgotten Broadway songs, wrote something like the following in one of his liner notes:
I've been asked why I am so facinated by love songs. I think it is because I can't love myself.
A man sticking his pecker up another man's anus performs an unhealthy act. We should try to discourage it. Those who do this are not heroes. They may be pited but they should not be honored.
Secondly, I have no problem with transferring health benefits, Social Security, pensions, inheritance tax waivers etc. to a widow because that widow very likely sacrificed herself to perform the most important job in society -- being a mother. I do have a problem with a man removing himself from the labor force so he can play house for another man.
With some of these things -- such as Social Security -- it might be better to change it so the benefits may be willed to whomever. And I certainly think we should get rid of the inheritance tax.
But this is not the status quo and homosexual men should not get any of the privileges of marriage since they can not bear any of the responsibilities.
The only reason for the state to involve itself in marriage is to protect mothers and children.
Marriage might actually be applicable concerning lesbians and artificial insemination. BUT, it should be recognized that this is a contract involving all of society, and those breaking it should expect to feel consequences.
That's what they used to tell women if they got raped - if it's inevitable, just lie back and enjoy it. But the better answer is to fight like hell.
I will presume you are a male freeper.
So to your statement above, I will say that it is only because you are not a young ripe 12 year old starting into puberty.
Therefore the gay and lesbian agenda taught in some schools of "how do you know unless you try it." will not be indoctrinated into your more mature brain.
You also state; "The other day I was talking to my Dad, who as a JP in Vermont is prepared to resign rather than perform a civil union." Then you said you asked him a few questions and in answer to your question, he agreed that he believed gays were born that way etc.
Then why would he resign before preforming the civil ceremony?
Anyway, religious opinion is not quite as simple as you seem to think. To give you an example, consider a Catholic discussion of the history of the institution.
