"Are we being judgmental in taking this position? Yes, but not of the motives of the persons involved, which Jesus forbids and on which He alone will render judgment, but rather of their actions, which are contrary to what the Lord teaches."
This is interesting. I've never seen this take on the "judgementalism". It's always been "how dare you ever judge anything!" At least these days, of a PC world. Which often include "Christians" always repeating the mantra of never "judging", which even means apparently never speaking out against their actions!
(I'm not a Catholic, so maybe it's normal for you all to see it as "motive" vs. "action", but I've never heard this delineation.)
So many people do not understand the Gospel about judgement.
Christ did not say "don't judge". He said, if you judge, be prepared to be judged by the same standard you are using; and that before you judge, first clean-up your own life (St. Matthew 7.1-5). He also said "Judge not according to the appearance, but judge just judgment." (St. John 7.24)
Christ's message is to live justly and judge justly, so that you can discriminate between right and wrong and thus be a light of right behavior to the world. Too many people are eager to judge others, but are not just with themselves. They condemn the sodomite, but wallow in fornication and adultery.
But if we did not judge, we could never apply this advice: "By their fruits you shall know them." (St. Matthew 7.16)
