Sexual practices are forbidden not because of the convenient rationales one often hears today, but because they are maasei mitzrayim, acts of Egypt, and thus taboo for Israelites, who are exhorted to live a life circumscribed by distinctions. The prohibitions are part of Leviticus’s “Holiness Code,” which is chiefly about maintaining cultic and ritual purity – not ethics, not family, and not “nature.”
