If anything, I'd say that - based on history and tradition with regard to the rights understood to be part of, e.g., privileges or immunities - abortion rights are a closer call than same-sex marriage rights. Still, I don't think the latter will be removed anytime soon.
I think gay marriage has been around long enough, and gays are enough out of the closet that society at large has at minimum a live and let live attitude. And it's more - gay couples have been around and are visible enough, that I think people just shrug. Even when I belonged to a religious cult - and they regarded it as sin - they were still of the attitude that they don't get the GOVERNMENT in on it. I do know of churches whose ideas believe they are charged with changing society - thus, they campaign against gambling and pornography and gay marriage and so on. Most evangelical and other similar churches - their approach is, you can't save souls by changing society - you change PEOPLE. Historically, changing societies has led to much worse results.
I'm not of the opinion that if you believe in a right, you must go look for one out of contorting the Constitution in order to FIND it. If you want a right in the Constitution to be guaranteed - you WRITE it, and pass it.
While in that church, I became VERY aware of the concepts of eisegesis and exegesis - strictly with respect to the Bible, but being the English language, I can only suppose they are used broadly, elsewhere. But for everyone else - exegesis is generally what I and a lot of people think SHOULD be done with the Bible - that is, to take from it what it means. You READ it first, and follow what it means. Eisegesis starts with you wanting to find the answer - and you LOOK for passages that you believe defend the idea. And a lot of people do this - they want to believe that, say, GAMBLING is wrong - so they scour Scripture to find "proof" of it. I remember challenging an evangelist on the concept of cannibalism - and aside the fact of KILLING someone first, he could not find "proof" that you couldn't eat humans that were already dead - until he found evidence in the Law where humans were "unclean" under the Old Testament, where I countered that Jesus - and Paul - declared all foods clean.
I've seen similar "arguments" for TRYING to insert rights where they weren't intended - for example, since Jews may not work on the Sabbatth but are allowed to make fire - rabbinical students once approached a famous physicist to ask if ELECTRICITY could be defined as "fire".
Hence - LOOKING for a right that was never given, hoping there was some "principle" that could be otherwise applied.
So I'm not cool with the idea of re-arguing an Amendment claiming the right is THERE. Even RBG said that she thought the basis for Roe was extremely weak. Then again, she offered alternatives - still doing with the Constitution what rabbinical students struggle to do with the Law.
