Actually, the biblical view is rooted in Genesis 1: "Male and female [God] created them." Jesus re-affirms this truth: "Have you not read that he who made them from the beginning made them male and female." Thus, there is an intrinsic, sexual complementarity between man and woman, which homosexual activity and transgenderism violate. The Levitical prohibition, while real, is actually subsidiary to the creation mandate. And you definitely cannot equate sodomy with eating unclean meat; the latter is part of the ceremonial law, done away with by the Gospel. The former is part of the moral law, which is never abrogated. 

Can you even tell me what natural law is?  

And your resort to ridicule actually betrays the weakness of your argument.
