Roe v. Wade is based on the 'right to privacy.' If the majority opinion by SCOTUS suggests that the constitution does not protect the right to privacy... that affects a WHOLE lot of other decisions. Buckle up - this is the beginning of a lot of potential ugliness.
Meyer v. Nebraska: This 1923 ruling allows families to decide for themselves if they want their children to learn a language other than English. This could open the door for racist states to try to outlaw learning their family's languages.
Skinner v Oklahoma: This 1942 ruling found that it's unconstitutional to forcibly sterilize people. The Roe ruling could open the door for criminals, disabled people or BIPOC folks to be forcibly sterilized.
Griswold v. Connecticut: Decided in 1965, this case protects the ability of married couples to buy contraceptives without government restriction. This isn't just about abortion. Next up, contraceptives.
Loving v. Virginia: This 1968 case, which threw out laws banning interracial marriages, was decided based on the right to privacy. If a state wanted to prohibit who people could marry -- there is no protection from that without a right to privacy.
Stanley v Georgia: This 1969 case found that there was a right to privacy around possession pornography. If a state wants to outlaw pornography or certain forms of adult pornography, it could do that without the right to privacy.
Lawrence v. Texas: Decided in 2003, the court used the Right to Privacy to determine that it's unconstitutional to punish people for committing ------. The Roe ruling could open the door for criminalizing homosexuality.
Obergefell v. Hodges: The 2015 opinion that legalized same sex marriage used the right to privacy and the equal protection clause to do so. This could open the door for a state to try to test same sex marriage laws.
