I hope you'll allow me to rephrase your comment to make sure I understand.
"Contrary to Justice Thomas's stated opinion, I am saying that his ruling is likely based in his religious views, and not on his judicial opinion of due process."
If that is a correct re-statement of your point, could you flesh it out for me? How did you come to that opinion? Are there other examples you can present of Justice Thomas "likely" passing rulings "based in his religious views"?
I am probably ignorant on this one- I look forward to your illumination.
Edit: I apologize at the top, this is a much longer post than I intended it to be.
I am specifically saying that his choice of cases that should be revisited is based in his religious views, not his legal views. His ruling here reflects his longstanding veiw that the constitution grants no right to privacy and that the concept of substantive due process is wrong.
Griswold established the "right to privacy"(not due process) which allowed Roe. Roe in turn expanded both the concepts of due process and right to privacy that would eventually allow for Lawrence and Obergefell to be decided.
He's arguing that, because the due process and right to privacy used in Roe is "demonstrablely erroneous", these cases that use these precedents should be overturned.
So, my reasoning for stating that has to do with religion and not his legal theory is based in looking at the cases he chose to use as references and how those topics are looked at by Evangelic Christians(EC) and Conservative Catholics(CC).
Pretty easy off the jump, both EC and CC are pretty anti everything homosexuality.
The topic of same-sex marriage(Obergefell) is still one that has significant push back in a number of states, most recently in the news was
Tennessee and the attempt to iintroduce a bill there that would create a seperate class of marriage just for hetero-couples.
Roe, Lawrence, and Griswold were all cited in this decision, so that's how they tie in here.
The same EC/CC mindset is likely why he brings up the case regarding sodomy laws(Lawerence). Now, outside of some real extreme religious circles, I've never seen any push to reinstate these laws. However, Thomas was on the court for this case; he dissented under the idea that there is no right to privacy (Griswold) in the Constitution. Roe was also cited in this case as well.
Lastly, contraceptives(Griswold). This one seems pretty out there until you spend time in CC circles. The official policy of the Catholic Church is still Humanae Vitae, which states that all forms of artifical contraception are inherently going against God's will.
This case was one of the first to establish the idea of a "right to privacy" and is vital to the other cases.
Now, from how Thomas writes his dissent, it's pretty clear he wants to overturn cases decided by the due process clause or "right to privacy".
Griswold makes sense from that prespective; it set a precedent which was later used in Roe and these other cases.
Lawerence and Obergefell don't though. They didn't really set any major precedent in regards to privacy or due process. The only thing that makes these two cases stand out from any other is that they both occurred during his time on the bench, he dissented in both under religious liberty and lack of due process views, and they both involve gay people.
You think if you wanted to revisit cases that started the right to privacy and due process, you'd go for both of the ones that set the precedent? That's what he's doing with Griswold and privacy.
Now, what case had the largest impact on the view of the due process clause that Thomas doesn't support? What played a larger role in Obergefell than Roe or Griswold? What helped expand the concept that caused the decision in Lawerence?
Loving V. Virginia
Loving was one of first cases to really expand due process to this level. The concepts of this case were fundamental in Roe, Lawerence, Obergefell, and basically every other case decided by "the due process clause of the 14 Ammendment".
If Thomas truly felt that the use of the due process clause is fundamentally flawed, this is the case to try and overturn. It's the first domino to overturning every other case he's dissented on those grounds.
Loving happens to be the case that legalized interracial marriage.
So if Thomas doesn't believe in this reading of due process and feels it should always be a state issue, why avoid this case? Overruling the precedent set here would negate Obergefell and Lawerence outright.
It's almost like his legal theory doesn't apply to cases in which he would be affected, but only in cases which don't match his religious views.
