Correct statement on both accounts.
I'm not a "miracles" type of guy, I'm really not. The thing about Fatima is that even if you're a scientist, apostate or believer of false gods it truly has the power to convert. It happened recently, in front of thousands of people and has there are no credible detractors. It truly was a miracle in every sense of the word.
A proper way to handle other (false) religions would be to have a process in place to get them there to attend a mass or maybe educate them as to what happened.
Putting their holy men up preaching err shows an unbridled contempt for our triune God. By giving believers of false idolatry any notion that what they're doing is correct we're not loving them, we're hating them in the worst possible way.
You've stated my thoughts so much better than I ever could. Thank you.
