I've made my case that "man as with a woman" is related to surrogate use rather than homosexuality per se enough times and then some. Some members are understandably getting tired of this. I should note the links and just cite them when another new person brings this up. Alas, the site is not searchable and it's a serious pain to dig them up.

But as for Leviticus, much of it can be reduced to a sentence or two: "don't be excessive like those Canaanites, stick to the optimum in everything and don't go for the bizarre (weird food, strange mixtures, sexual combinations that go against natural incest queasiness, sex at times when partners are issuing blood, etc.), or to put it into local terminology, "be circumcised." Take off the 5% of extra loose fleshly pleasure in everything; to borrow a phrase from Deuteronomy, "circumcise the heart."

In a nutshell, incest, extra marriages, bisexual recreations, screwing around with animals, etc., all fit right in there with making mixed fabrics as way-out, flappy excesses. God-given good-enough is good enough! On the other hand, gay love to a gay person is not an excess but a centrality, and to circumcise it away would be to take the whole organ off, not the foreskin. Well, penectomy, unlike circumcision, manufactures deformity (see below), so that is not in keeping with the spirit of Leviticus.

Sometimes the quest for optimality in Leviticus went so far that we're relieved now we don't need to take it literally, e.g.,

"16 Then the LORD spoke to Moses, saying, 17 “Speak to Aaron, saying, ‘No man of your offspring throughout their generations who has a defect shall approach to offer the food of his God. 18 ‘For no one who has a defect shall approach: a blind man, or a lame man, or he who has a disfigured face, or any deformed limb, 19 or a man who has a broken foot or broken hand, 20 or a hunchback or a dwarf, or one who has a defect in his eye or eczema or scabs or crushed testicles.'""

These days we will generally accept a person with some contact dermatitis or a blind person as a priest or minister, and I don't think that even on this site we will find anyone who thinks our acceptance terribly lax and wrong. (:-S ).
