Why is Homosexuality wrong? Did Jesus ever mention anything about homosexuality?

Where do we get the moral law? 

Who has the moral high ground in the discussion of sexuality and pleasure?

As Christians we don’t keep the “Clobber Laws” today. The Levitical Laws prohibiting such things as blending two types of fabric, or tilling the ground and sowing two types of seed, eating crustaceans…or men sleeping with men as one lies with a woman, so how can we pick and choose our morals?
