After reviewing the vast majority of comments, a few things leap out:
a) the editorial stance highlighted the lack or inconsistency of USCCB statements and called for that....most comments completely skip over that FACT
b) too many commenters shifted to 2nd Amendment - guess what?  This is a SCOTUS legal interpretation and even legal experts are careful about statements around what Scalia did in skewing the track record of SCOTUS on guns and 2nd Amendment.  This is NOT settled law - a change in SCOTUS may lead to different future outcomes.   Chief Justice Burger publicly stated that the Scalia interpretation was just a bunch of made up revisionist history (originalism?).  We could post until the cows come home and find legal briefs on both sides - non-starter if that is what you base your editorial comments on
c) there is no data in most comments - without evidence, opinion is not well informed
d) sorry, global gun control efforts put the *lie* to how this would not work in the USA
