Bethy, you appear to not be aware of how seriously we take our freedom of speech here. You are free to say anything you like. We are free to disagree. If you up the ante, we will respond.
So is the Holy Father free to express his opinion, even (horrors!) about events in YOUR COUNTRY. As are we.
If you come on a thread with a troll comment, or a baiting comment, you will get a reaction. (*I’m offering 3rd grade psychology, here*.) If you want to fight about religion, you will get takers.
I don’t have a desire for conflict, but it is tempting, when you appear to take offense at others exercising the SAME free speech you demand.
