You're not wrong. In fact, I was just reading this: "[In] a statement from Slate reporter Mark Joseph Stern pointing to passages in the draft opinion… “Alito’s draft opinion explicitly criticizes Lawrence v. Texas (legalizing sodomy) and Obergefell v. Hodges (legalizing same-sex marriage),” Joseph wrote. “He says that, like abortion, these decisions protect phony rights that are not ‘deeply rooted in history.’” [quoted from *The Hill*]
By those metrics, the Civil Rights and Voting Rights Acts qualify as "rights that are not 'deeply rooted in history.'"
