My family became traditional when I was a toddler, so I can't answer your questions directly, but:

2. They thought we had gone crazy and joined a cult. I suspect this is a very common reaction in this situation.

3. Most definitely.

4. No.

1. I grew up among cultural Catholics who, after the oldest generation was gone, were lukewarm/indifferent. I knew nothing about V2 till after I reverted a couple years ago in a road-to-Damascus sort of way. (Lockdowns + big life changes, Divine Providence to the rescue.) When I returned, the NOM just felt really wrong on a visceral level. It reminded me of the horrid 1970s but also, thankfully, of how much better it was way back when I was still too little to get it. I started researching and looking around, and it all clicked.

2. Two factors, they're attached to person-centered practices, and they're reluctant to face up to what Tradition teaches about sin. 

On the first factor, something like thinking it's OK for women to lead the Rosary if there's an adult male present; if they can't even see that the women shouldn't so much as take turns leading the decades, then they'll resist the truth of the far more serious abuses in NOM liturgical and Eucharistic practices. On the second factor, the conciliar false shepherds have condoned so much that we know to be disordered and blasphemous, thus people use that as cover for skipping Penance and for making excuses for what they see around them every day.

3. Absolutely. People can't/won't deal with being confused/isolated, so they'll stick with what's familiar over what's right. Choosing Tradition means having to shun certain social situations and stand firm no matter how lonely it gets. Sometimes you have to explain yourself calmly and clearly out of charity to those closest to you, sometimes it's better to stay silent. Pray to the Holy Ghost for guidance! 

4. With each other? No. 

1. Was brought up going to Mass, non-negotiable in my home, but didn’t really know anything, thanks to non-existent catechesis.  Questioned everything in college and started on 30 year spiritual journey wherein I almost systematically explored every flavor of Protestantism, with exceptions of groups such as Mormons, JW’s, etc.  All were found wanting.  I read, read, and read some more until I came to the conclusion I believed what Catholics were supposed to believe.  Went to novus ordo for maybe two months, weekday Mass in evenings, was disappointed.  Keep in mind I’d never heard of Tradition although I did know Mass used to be in Latin, and I had vague memories of attending Mass in Latin with my grandmother on visits when I was very young, like ages 2-4 years. I’d purchased a Fr. Lasance daily missal and had begun trying to study and use during novus ordo!  It was nearly impossible and why was there the Jєωιѕн blessing over bread in English at the consecration? I can recite it in Hebrew, and why wasn’t there the same over the wine?  I quit going to the novus ordo and to church altogether.  At that point, I was “invited” as one of a group of about 20 people, to a temporary work colleague’s son’s Confirmation.  She was an odd woman that others at work made fun of behind her back and a few even deliberately excluded her from casual socializing. I despise this sort of thing, cliques, cattiness, gossip, backbiting, and decided to go.  I didn’t know her very well and didn’t know her son at all.  To my astonishment, I found myself at a Latin Mass!  After the Mass, there was a reception at which I introduced myself in terror to that scary British Bishop whose sermon had put the fear of God into me.  I had a dozen questions for him scrawled on a piece of scrap paper.  I needed to know the answers, like, immediately!  After a second impromptu conference, he graciously gave me about 45 minutes of his time, calmed me down, and answered them. The rest is history.  
2. The question is no longer applicable since my parents passed away.  And even they wanted the Sacraments in the Latin Rite when they became ill and homebound.  The rest of few remaining family are “not religious,” the one surviving older relative Baptized, the rest, no.  When filling out docuмents that ask for religion, they write that most numerous of American creeds, “none.”  
3. From what I’ve observed from childhood onward, the majority of humans take decisions in packs.  Yes, I have lost the few close Protestant friends I had, my remaining family don’t care about my religious practices, and I lost my job and ability to earn a living for refusing Dr. Fauxi’s remedy.  I’ve always been the odd one out dating back to Miss Fernandez’s Nursery School.  So nothing has changed in that arena.  
4. I’m friendly to almost everyone unless/until there’s a reason not to be.  I can’t really say as I’m not involved in any close social circles involving SSPX and Sedevacantists.  I’m not sure how to categorize myself on that issue, but I will state that I do not participate in fights over it.  

1) I was Protestant, anti-Catholic in fact, until 2011. I had a friend in college that I would argue with a lot about Catholicism. He was Catholic. One time he told me something that bothered me so much I had to prove him wrong. It sent me down a rabbit hole and I ended up reading a lot of books and came to the conclusion I needed to be Catholic. So I went to the nearest Mass to me. The priest gave me the creeps. He had pasty white skin, dark eyes, and he spoke in a mono-tone almost. He was beyond ho-hum. But I kept going to Mass for a few weeks because I was convinced I needed to be Catholic. When I contacted the priest and told him I wanted to be Catholic, he said, “Ok, classes start on X date.” That’s it. So I called up my friend and told him he was crazy if he thought anyone would want to be Catholic after going to Mass. There was a long pause and then he told me I needed to go to A Traditional Latin Mass. Annoyed, I asked him why he didn’t tell me that in the first place and he admitted it was because he didn’t know if I was ready to hear about the crisis in the church. He didn’t realize my local NO parish was so bad.

So I went to a TLM Mass and was stunned speechless.

I went home and I prayed the Rosary for the 1st time. It took me 1.5 hours to get through because I wept at every Hail Mary. I knew I had arrived and there was no looking back.

2.In my case, none of my family was Catholic. However, I knew a lot of NO Catholics. They don’t want to make the switch to tradition because it is too arduous. It would mean no more NFP for birth control, it would cause disruptions with their friends and family and it would cause them discomfort in their comfortable religion.

3. Absolutely. It is hard to reject family customs and swim against the tide. It is especially hard for young unmarried women. Or maybe I just think that because that’s what I was at the time. Our Catholic lifestyle puts considerable strain on family relationships and makes it hard to find friends. 

4.I’m not sure.
