> Roe vs. Wade wasn't about abortion, it was about privacy. That's why they're already talking about voiding gay and interracial marriage bans, they were based on that precedent.
This is factually untrue in the case of interracial marriage and deceptive in the case of gay marriage.
Loving v. Virginia, (which predates Roe) prohibiting bans on interracial marriage, was based on marriage as a fundamental right and the Equal Protection Clause of the 14th Amendment, not privacy and substantive due process like Roe. A Roe-like substantive due process argument was raised in Loving but not resolved by the Court because the EPC argument was sufficient.
Obergefell v. Hodges, prohibiting same-sex marriage bans, had two independent bases, an EPC basis resting on Loving and a substantive due process bases resting on Roe and related cases. (In Obergefell the Court didn't choose not to resolve the substantive due process argument despite the EPC being sufficient, unlike Loving.)
In strictly reasoning-of-the-case terms, Roe (or even, as Justice Thomas has suggested, the line of substantive due process cases on which Roe relies) being struck down has no impact on Loving and no decisive impact on Obergefell.
The real reasons these and other cases are talked about as targets isn't legal reasoning, it is power politics: both the left and right see an activist Court that has proven multiple times recently that it is willing to ignore settled precedent to write right-wing preferences into law, and one side is afraid of that and one side wants to maximize the benefit they can extract from that situation while it lasts.
