All right. Let's address what TexasTig is actually saying, as opposed to the rhetoric he cloaks it in.
There are men (and probably women too who force, coerce, or seduce children into same-sex acts. True statement. It happens -- IMO, it happens far more often than most people would wish to believe. It's immoral, criminal, disgusting -- adjectives fail. They are called pedophiles. (To be extremely pedantic, those who prey on prepubescent children are pedophiles (paedophiles in the UK); those preying on adolescent males are ephebophiles, and on adolescent females, hebephiles. The only point to making this distinction is that they are three distinct paraphilias, with different etiologies. The man who wants sex with young teens is probably not interested in children before they reach puberty, and vice versa.) The typical person who identifies as gay or lesbian is not one of these; odds are he or she is as disgusted by it as the heterosexuals who confuse him or her with them.
The term 'homosexual act' is applicable to such behavior, but only in a dictionary-definition way -- it is not what someone identifying as homosexual regards as an acceptable homosexual act, which for him or her is between consenting adults, and ideally ones in a committed loving relationship. A somewhat risque joke which I would otherwise not post here may serve to help make this point: The elderly shepherd was arrested for having sexual relations with some of his sheep. At his arraignment for inappropriate behavior with animals, he protested that it was only with the ewes: "I'm not a pervert!" he exclaimed. Just as his definition of 'pervert' meant that he avoided the rams, which would be 'homosexual' conduct, gay people are appalled at the idea that sex with a non-consenting child might be regarded as 'homosexual' even though the broad definition of the word would include it. It would be like equating a chaste married couple's sexual relationship to that of a molester of little girls, because both are technically heterosexual acts.
Some children enjoy sex with adults. True; unforced, uncoerced sex is generally pleasurable, and children can respond sexually as a general rule. Any mother or father who has washed a small boy's privates and seen him grow erect under the (unintentional) stimulation of the washcloth is aware of this. (I understand the equivalent reaction happens in young girls, but have never given a bath to my honorary granddaughter so I cannot speak from experience here.) Typically, a child molester deludes himself into mistaking this for consent. And, because of the onus placed on homosexuality in today's society, many molested children come to believe themselves to be gay. But, and this is most important, this is carnal use of another for one's own gratification, whether sexual or dominance -- not consensual sex. There is no doubt some point at which an adolescent becomes capable of mature consent, but I don't even want to discuss that -- just to note that it's not a magical crossing of the maturity line at some legally-specified birthday.
And it is quite possible that the only persons TexasTig has known to be homosexual, in the broad sense of the term, were his molesters. I'm quite sure he has known other homosexual people, but given the circumstances, I suspect strongly they did not let themselves be known as being gay.
There is a cottage industry engaged in generating fraudulent statistics to support the anti-homosexuality crusade.. Paul Cameron of the Family Research Council is a typical example. He has a perfectly valid statistical set showing that, according to him, most homosexuals have sex with multiple partners, have greatly reduced life spans, and a chance approaching certainty of contracting deadly STDs. What he doesn't say about this data set, which as I said is valid for the purposes it was constructed, is that it represents gay men hospitalized in San Francisco in the early days of the AIDS epidemic, before anyone knew what was causing it. He is also reportedly the only researcher ever expelled from the APA for falsifying data. People such as minor-party Presidential candidate Alan Keyes, James Dobson of the Focus on the Family propaganda empire, Donald Wildmon of the so-called 'American Family Association,' and the man who runs 'Concerned Women of America,' have continued to use this sort of corrupt data even when it has falsehood has been demonstrated to them with documented proof.
Thou shalt not bear false witness against thy neighbor (Exodus 20:16) And when they asked Jesus, "Who is my neighbor?" He answered, "A certain man went down from Jerusalem towards Jericho...."
I still have yet to see a convincing arguement that can adequately explain how a relationship between two consenting adults can be likened to situations where the other person is completely unable to give consent. 
The fact is that different Christians believe different things about marriage.
