Well Pan,  I could offer your own advice back to you when those with whom you normally agree are uncivil or outright rude,  and you say nothing to correct them.   It runs both ways.  

However, when folks post comments that cast aspersions on the Catholic faith of another person or entity, verbally or with lower case "c" in NCR, etc.,  ...  that is where I draw a firm line.  I ignore a lot of the rude and inappropriate  posts on ALL sides,  often skipping over them,  but I won't ignore abusive comments/digs about a person's faith.  NO ONE has the right or authority to do that.   My correction to Eliane stands.  Her use of "NcR" is a tacky backhanded slap at a publication's website where she routinely returns to post ugly comments,  and also her slap at the other folks who come here to read and post comments.  She is also fond of labeling those with whom she disagrees as the pejorative "dissenters".  Enough already.
