I could hang out with Eric Dubay and get along *famously* with him, as long as Religion never came up. If we could avoid that topic, agree to disagree, he could be a very good friend.
Meanwhile, there are many Trads that I would have a hard time getting along with *most* of the time. Unless we were at Mass, Benediction, or Catechism class, there wouldn't be much we could find in common! Maybe it's the lukewarm or superficial Catholics who are like this -- who don't allow the Faith to sink into themselves at all, instead keeping it at skin level?
Maybe it's a question of natural vs. supernatural virtues?
I once did software development work for a Jєωιѕн man. He prided himself on being fair -- and indeed he was. He didn't take 1 cent from me that was mine. He fired me completely out of the blue, and refused to give me a reason -- but he paid every cent he owed, without any arm-twisting.
Meanwhile, a fellow Trad (and friend) borrowed a couple thousand from me to buy a family vehicle -- and then decided to cut off the friendship, rather than pay back the money. No, there's not "another side" to the story. He didn't even ask me for more time, I wasn't being pushy at all, etc. He just ghosted me, and when I asked nicely when he was going to make a payment on the debt, his first words were, "I'm done. Friendship over." Our 2 (large) families were *friends* with each other. Not just on Sundays, but doing tons of socializing together: staying at our house, working on projects, etc. for several years. Amazing how he would throw all that away for $2K. He probably stole a large gift card someone donated to the chapel as well -- I didn't suspect him at a time, because I didn't know he was a thief.
So you have this Jew who is very good at "Thou Shalt Not Steal" and a Trad (who converted about 25 years before I met him) who is horrible at that commandment -- as well as the 8th Commandment, for what it's worth.
Just goes to show you that natural virtue is independent of having the Faith. It's a separate thing. Muslims are often great at Temperance (avoiding alcohol, smoking, drugs).
