This is a real concern. The Supreme Court Justices were all specifically asked about Roe during their confirmations. They ALL stated that Roe was “settled precedent”. The minute they got a majority in the court, they voted the opposite to what they had said under oath during their confirmation hearings. This does not ethically sit well with me.
As you say, conservative states Kansas and Ohio have held referendums and both had results allowing women the right to make these decisions with their medical professionals. No surprise there, as the majority, even Republicans, believe in keeping abortions safe and legal. Having seen the Kansas and Ohio results, I do not believe that the state governments in Alabama, Arkansas, Idaho, Indiana, Kentucky, Louisiana, Mississippi, Missouri, North Dakota, Oklahoma, South Dakota, Tennessee, Texas, or West Virginia will put this to a referendum. So no, “the voters in those states have every avenue to change the law if they wish,” as you say, is not actually true. In the meantime, a 10 year old rape victim in Indiana had to travel out of state to get her treatment. And there’s Kate Cox in Texas, who devastatingly found out that her planned pregnancy had gone horribly wrong, and was denied the treatment she required, despite being medically advised that the longer her pregnancy carried on, the more she was at risk of never being able to have a child in the future. She took her case to court and lost, so had to travel to get the medical treatment she required.
Women have had reproductive rights for 50 years, and it feels quite cruel that you’re happy to now dismiss them with, “they can advocate at state level if they wish.” The 10 year-old Indiana girl can’t even vote!
