Yes. The only thing that would catch public attention would be a dramatic act such as the excommunication of someone like Biden. But the time for that may have passed.
In one way you're right, the time may have passed. In another, though, this is the ideal time much more than prior to the election would have been. Biden is part of an administration that was just reelected with the help of Catholics. Catholics who had no real reason to know they they shouldn't vote for the pair. Sure, they have plenty of excuses and can complain that the Bishops weren't clear enough, their individual parish is liberal and didn't read even a watered down statement from anyone, and so on.
Those are excuses, though. Even the government itself has made it clear they are going after the Catholic Church as an instutition. Plus, who can honestly say they don't know the Catholic Church condemns both abortion and contraception?
Troops willing to fight march toward the sound of the guns, not away from it. Nothing would magnify the sounds of battle more than the very public excommunication of Biden and all of the other pretend Catholics in Congress and the administration. Besides, anyone who is a party to mass murder should at a minimum rate being included in a public proclamation listing those who by their actions openly deny that they are Catholic and ends with "Let them be anathema" shouldn't they?
The Federal government has already declared war on the Catholic Church and it was a CINO who chose where to fight the initial battle. It's obvious that a large number of those who claim to be Catholic have either already sided with the enemy or have no stomach for battle. Give those who are faithful the sound of battle as a signal that the Church intends to fight rather than the near silence of shuffling legal briefs and toothless proclamations. The noise of battle might even wake up a few of those who didn't vote for Barry and Satan, but didn't bother to vote against them either.
JMHO, and hey, I'm new at this Catholic stuff so what do I know?
