Like I mentioned elsewhere, a rewritten Equal Rights Amendment expanded to include sexual minorities:
"ARTICLE —
"Section 1. Equality of rights under the law shall not be denied or abridged by the United States or by any State on account of sex, gender, or sexual orientation.
"Sec. 2. The Congress shall have the power to enforce, by appropriate legislation, the provisions of this article.
"Sec. 3. This amendment shall take effect two years after the date of ratification."
What would that do that the 14th Amendment doesn’t do already? Why not codify substantive due process and rights to autonomy/personal liberty?
