I don’t understand what you mean by Trad culture. What is that? Traditional Catholic recognize that the Faith is inherently attached to Tradition. Therefore, since they let Faith run through every part of their lives, they let Traditional standards, disciplines, teachings, etc, influence them in every detail. We don’t watch bad movies, don’t expose ourselves to occasions of sin around the opposite gender, recognize that men lead and women follow, follow pre-Vatican II disciplinary practices, etc.
If you don’t like certain aspects of Traditional culture, like the smoking cigars and drinking hard alcohol, then that’s okay. I would personally expose my voice to smoke, either. But one cannot comply brush aside “Traditional culture” because they’re comfortable with their place in the world. I notice it a lot in Sedevacantists, where they’re very strong in the area or doctrine, and very adamant about holding the True Faith, but extremely lax in areas of modesty, having gentlemanly or ladylike comportment, etc. This is not something we should do. Of course the Traditional Faith is essential. But how much better is the Faith if it’s lived in every aspect of your life?
Nobody is saying that we have to live exactly as we did in the 1950s. Literally no Traditionalist can because we all have computers, phones, modern cars, etc. We are normal people, not in the sense that we fit in with secular society in all its evil, but in the sense that we just live our lives the way humans should with a very keen eye for how every aspect of our lives ought to be. We are modern Catholics, not in the sense that we’re modernists, but in the sense that we’re Catholics living in the 21st century. We live in the modern world, during the Crisis in the Church, because that’s the age God put us in.
We shouldn’t just go with the flow of the 21st century mainstream culture, though. We can treat them with charity, and pray for them, but we need to root out every little aspect of our lives that is attached to modernism. That means disciplines, too. Is that not how one grows in virtue, after all? Not just by obeying God in doctrines and rooting out major sins, but also the minor flows which weaken our souls little by little.
If you don’t like the 1950s aesthetic, then that’s fine. The Catholic standards are unchanging, but the Catholic application of standards has always changed in Catholic society within the realm of acceptability. If I wear jeans and a polyester shirt now, I’m still fitting the standards of Catholic modesty. But if I wore that in the 50s or before then, they would consider my outfit immodest, despite the coverage. But consider that people in the 50s would be considered immodest by people in the 1850s, as well.
We can recognize ideals versus standards in disciplinary areas. The ideal may be for me to wear a collared button shirt with some nice pants, instead of my jeans. Because the fabric is better, it’s more gentlemanly, etc. But I don’t sin by choosing the jeans and polyester shirt, because both outfits fit the standards of modesty. I understand that some Traditional Catholics attach sin or moral unacceptability to ideals which they wrong view as the standard, or the level that ought to be reached, but one must be patient with them. You can’t chalk that up to being every Traditional Catholic and therefore all of “Trad culture”. Yes, of course Traditionalists aren't Puritans. But that's because we aren't heretics. Heretical sects getting moral questions wrong doesn't mean we should ignore the standards and principles the Church has always laid down. We an recognize that the application of those principles changes within the realm of Catholic acceptability, but the standard always remains the same.
