[DRAFT] U.S. Obscenity Ban: Name & Blame
An 1873 federal bill to ban smut, abortion pamphlets, and sex toys was never found unconstitutional; instead, only the clauses that meaningfully impacted the ability of the American public to be sexually promiscuous were overturned, piecemeal, under the banner of "civil rights".
