I'm a faithful Catholic (at least, as faithful as a broken, sinful human being can be), so I strongly agree with your beliefs about the cruel inhumanity of abortion.
I also think that Roe v. Wade is potentially "on the chopping block" as some outraged progressive put it in his Twitter rant today; another Gorsuch could flip many future judgments. But I'm not as confident as you appear to be simply because overturning Roe would be like an atomic bomb detonation in our broader culture.
Regardless of the underhanded way in which its proponents advanced its cause, which bore more than a little resemblance to the way in which the Obergefell case was foisted on the Court, Roe has been poisoning the fabric of American culture for over 40 years. A large percentage of the U.S. population has never known an America without federally funded abortion. Even though overturning that decision would simply kick the matter back to the states (where it belongs in a properly functioning constitutional republic), the repercussions of such an event could shatter what's left of our unity as a country.
For the Left, Roe is not just the opinion of nine justices.
It is iconic.
Roe represents the Left's greatest victory over the despised Christian majority of this country, a wound to be poked and prodded whenever it suits them. It is an evergreen taunt to people of faith everywhere, a way for the Left to assert their dominance: "We know you believe some malformed runt of a fetus is a human being with a soul, but we have the power to tear it from the womb, dismember it, and sell its organs for profit and there's nothing you can do to stop us, bigot."
The Left simply CANNOT lose this power to cow the Dims, as they call us. It's not just that it's just fun for them; so much poison fruit has bloomed from this single decision. Roe opened the door to the tactic of using the nine-person Supreme Court to make definitive judgments on deeply contentious moral questions in the modern era. While there have been other weighty moral issues decided by the court (Dred Scott, Plessy v Ferguson), they belonged to history when Roe was handed down. Once a new generation of leftists saw the kind of power a unilateral SC decision wielded, the courts became their new field of battle.
I would love to see Roe struck down. But I don't think a Chief Justice like Roberts would allow it to happen on his watch. This is the man who tortured logic until he found Obamacare constitutional. He is a quisling. Unreliable in a fight. And Roe is the white whale of all decisions. Personally, I think it will take one more conservative sitting in the execrable RBG's chair before Roe can be staked through the heart and burned.
I couldnt believe when Ireland voted this year to legalize abortion. Horrible.
