Some folks seem to delight in being absolutely outrageously . . . unaware . . . to put it extremely mildly.
I joined FR in Asia. Had I been in one of my duty stations there, a lot of what I typed would have been a serious hazard to me and definitely a serious hazard to those I related to about spiritual things and other things.
Most of me doesn’t give a rip that some rabid clique sorts of folks do not seem to have the where-with-all to wrap their understanding around such facts.
I guess some folks will just have to break their arm slapping their backs over how wonderful their cluelessness is.
Then it is hypocritical of you to demand that any Catholic defend his/her faith, when you will not even identify yours, much less defend it.
So, go look up anything you want, in the Catechism. It’s online.
