Parashat Achrei Mot Its Against Nature!

"Its against nature!" is something we've all heard regarding laws in the Torah against homosexuality and beastiality. This week's Torah portion Parashat Achrei Mot has many laws of forbidden relations, and while homosexuality and beastiality are against nature, other laws of arayot, while they use to be taboo, are completely natural, but still forbidden. These abhorrent customs were the reason why the Egyptians were destroyed and the Canaanites were expelled from the land, and avoiding them is a vital part to becoming holy, and going to Gan Eden.
