Most (I think all but one) of the references in the NT to S&G do not specifically reference their sexual sin, but rather are used to describe the severity of punishment others will receive for sins that have little or nothing sexual in nature, such as rejecting the word of Christ.
IOW, the references are used not to reinforce the idea that homosexual sin is more sinful than other types of sexual sin, but rather as an illustration of severity of punishment.
OK each to his/her own thinking. But, Sodom (where our modern word sodomy comes from) and Gomorrha was a specific act that brought forth a specific judgment. Every time I read those words throughout the whole of the WORD I do not think of other 'types' of sin. And what was Lot's wife's sin??? I do not recall that she participated in the perversion but she sure did not mind living within the confines of the perverted.
To me the Ten Commandments are a fairly basic set of laws. AND since Christ became the one and for all time perfect blood sacrifice, each individual has direct access to the Heavenly Father for forgiveness upon repentance. We all fall short.
