Beware the authority to which you appeal. SCOTUS also ruled in favor of forced sterilization, with reference to its earlier ruling on forced vaccination as supporting precedent:SCOTUS says otherwise.
It is better for all the world if, instead of waiting to execute degenerate offspring for crime or to let them starve for their imbecility, society can prevent those who are manifestly unfit from continuing their kind. The principle that sustains compulsory vaccination is broad enough to cover cutting the Fallopian tubes. (Buck v. Bell, 1927)
SCOTUS may have the power to decide legality, but legality and morality are not synonymous. Much evil has been done in pursuit of the "common good." Just food for thought.
