I would say this is exactly contrary to the Scriptures rather than supportive of them. Homosexuality is not a special level of sinfulness, as many social conservatives would contend. It is sinful no doubt, as is rage, bitterness, discontentment, unkindness, etc. But these are all SYMPTOMS of idolatry, which is the sin beneath the sin. Homosexuality is the result of rejecting God and his word and worshipping something else. It is a result of dethroning God in one's heart and substituting one's own choice, pleasure, desires, political ideology, whatever. This is no different or more offensive than heterosexual immorality because the root sin is the same.

I think we in the conservative church would do well to stop trying to diminish our own sins by comparing ourselves favorably with those struggling with homosexuality. We are just as guilty at the root level, and perhaps more so because we frequently disbelieve God's promises and reject his rule in our lives even though we have much more light from God's word.
