Are you sure? Because in his concurring opinion in the Dobbs decision said that contraception, same-sex marriage, and same-sex intimacy were wrongly decided and needed to be reconsidered.
Specifically, that he would do away with the doctrine of “substantive due process” and explicitly called on the court to overrule the watershed civil rights rulings in Griswold v. Connecticut, Lawrence v. Texas and Obergefell v. Hodges.
What's important about those cases?
Griswold was a 1965 Supreme Court decision that established the right for married couples to buy and use contraceptives.
Lawrence was a 2003 Supreme Court decision that established the right for consenting adults to engage in same-sex intimacy.
Obergefell was a 2015 Supreme Court decision to establish the right for same-sex couples to be married.
All 3 cases, along with Roe v. Wade and Planned Parenthood v. Casey, established a legal right to contraception/intimacy/marriage/abortion care, all of those cases relied heavily on the doctrine of substantive due process.
Where does that doctrine come from? It comes from 1 specific case; Loving v Virginia.
What's important about Loving v Virginia (aside from establishing that doctrine)? It's the case that said interracial marriage was legal.
So, in order to do away with the doctrine of substantive due process you have to overturn that specific case that established that docrtine- Loving v Virginia.
Which means interracial marriage can be made illegal again.
So, did he explicitly say that? No. Did he mean it? Yes. He's a Supreme Court Justice. He knows exactly where that doctrine came from and what would be required to overturn it.
