acceptable or sinful?

I stumble upon a gay-friendly christian blog and the quote below really hits me hard.

"The emotional, relational aspects of same sex love that a homosexual desires is genuine and is not evil in itself. But the sexualization of that desire is a sin. In other words, a person who has same sex attractions needs the love of a brother or a father but because of his sinful nature, his state of fallenness in Adam, these genuine emotional and relational needs have become a cause for sexual arousal...

...All he knows is that he desires to be close with a man, to be intimate with someone of the same sex - to have a bonding that will heal a feeling of emptiness inside." (by Rik of Journal of a Battling Christian)
