Here is my experience.
I decide, after months of consideration, to go to the local SSPX chapel for Mass. There is a dress code posted on the wall just inside the entrance. I noticed it as soon as I stepped inside. Coat, Tie, and Jacket.
I made eye contact with an usher, and he smiled, welcomed me, and offered his hand in friendship. I introduced myself as a guest.
I wasn’t wearing a coat and tie, but he didn’t say a word about it. He opened the door to the Chapel and invited me to sit anywhere I like. Once I was in the pew, I noticed a gentleman in front of me wearing bluejeans, work shirt, and suspenders.

And a couple of other men I noticed weren’t wearing ties or jackets. So I felt very comfortable at that point.
Wonderful High Mass, stunning choir, and the children ! It was wonderful to see school age children actually praying the Mass. No fidgeting, looking around, whispering. Definitely not what I was used to seeing. Teen girls in football jerseys, high school t-shirts, and worse. Sure the preschoolers were restless. Babies crying.
One 3 or 4 year old in the pew in front of me kept turning and smiling at me. I’d smile back and then return my thoughts to the Mass. Finally, we were kneeling and I showed him my folded hands and nodded toward the altar. He then folded his, and looked toward the altar. He turned his head and smiled, and then continued to look toward the altar. I’ll never forget that.
Anyhow, after Mass, I checked out the bookstore and picked up a couple of volumes of St Alphonsus’ works, then walked back to the cafeteria. The man that greeted me, had mentioned coffee and cake was served after Mass. A nice lady introduced herself and welcomed me to the Chapel. We chatted awhile, and she introduced me to a few folks, including her husband and the priest.
I left without hearing a single word from the pulpit or otherwise about VII, the Novus Ordo, or any other divisive topic. I was only asked if I was a Catholic.
And after assisting several Masses there early last year, I can say I prayed with Catholics.
