Then they aren’t Catholics.
Not your call. .the one duty of the multitude is to allow themselves to be led, and, like a docile flock, to follow the Pastors." - VEHEMENTER NOS, an Encyclical of Pope Pius X promulgated on February 11, 1906. "to suffer themselves to be guided and led in all things that touch upon faith or morals by the Holy Church of God through its Supreme Pastor the Roman Pontiff," "of submitting with docility to their judgment," with "no discussions regarding what he orders or demands, or up to what point obedience must go, and in what things he is to be obeyed... not only in person, but with letters and other public documents ;" and 'not limit the field in which he might and must exercise his authority, " for "obedience must not limit itself to matters which touch the faith: its sphere is much more vast: it extends to all matters which the episcopal power embraces," and not set up "some kind of opposition between one Pontiff and another. Those who, faced with two differing directives, reject the present one to hold to the past, are not giving proof of obedience to the authority which has the right and duty to guide them," "Nor must it be thought that what is expounded in Encyclical Letters does not of itself demand consent."

Rome manifestly considers infrequent Mass attenders and even proabortion, prohomosexual public figures (Teddy K RCs) to be members in life and in death. RCs then it is demonstrating its interpretation of Canon law, which is not for you to do. Instead, you are to consider such to be your brethren as Rome does, or become one of the schismatics. Which seem to be the case with most vocal RCs here.
I am one myself as a evangelical, former RC, praise God.
The redeemed are those who have been spiritually born of the Spirit (Jn. 3:2-7) by effectual, penitent, heart-purifying, regenerating faith in the Divine Son of God sent be the Father to be the Savior of the world, (1 Jn. 4:14) who saves sinners by His sinless shed blood, on His account. And which faith is imputed for righteousness, (Romans 4:5) and which is shown in baptism and following the Lord, (Acts 2:38-47; Jn. 10:27, 28) whom they shall go to be with or His return (Phil 1:23; 2Cor. 5:8 [“we”]; Heb. 12:22,23; 1Cor. 15:51ff'; 1Thess. 4:17) In contrast to those who were never born of the Spirit or who terminally fall away. (Gal. 5:1-4; Heb. 3:12; Heb. 10:25-39) Glory and thanks be to God.
