Enact a federal law that says:
Only a man and a woman may be married in the United States. Attempting to create a person by any means other than the union of a sperm of a male person and an egg of a female person shall be a crime punishable by a $10 Million Dollar fine and 20 years in prison. Marriage approves and allows procreation of offspring. No state shall prohibit a married couple from procreating offspring using their own unmodified gametes, or declare a couple married that is prohibited from procreating offspring.
Congress needs to take this step to preserve natural reproduction and marriage rights and prevent dangerous and unethical attempts at same-sex and transgendered reproduction, and avoid the unnecessary expense of entitlements, research and regulations.
