You are not answering the question, but instead seeking to dismiss it altogether (e.g., by making statistical arguments which suggest courtships between vaxed and unvaxed trads are unlikely in the first place).
Its as though you don't want the issue to be relevant, but you never address the concerns adduced above in cases where the vaxed and unvaxed are or will be courting, preferring instead to pre-empt the possibility of two such trads coming together at all (or suggesting that the number of such courtships will be so few as to not be worthy of consideration, even though these hypothetical few will also have souls to save).
OK, then leaving aside the fact that every SSPX teacher in New Zealand is vaxed, and that we've all probably known those SSPXers who say they'd take the jab rather than watch their families (allegedly) go hungry, for the sake of argument, let's stick with your 10% vaxed number:
In these courtships, is vax status a pertinent issue? Why or why not?
It's pretty simple. In a world in which the small percentage of Trad men or women are very
likely to be sterile or have cancer or auto-immune diseases show up, then 100 million Americans are also since the vaccine won't distinguish between the religious and non-religious. That is a whole different world.
Vax status is pertinent IF there are long term effects from the vaccine
of course. I would not marry someone with a greatly heightened chance of dying in middle age, assuming a normal world of mortgage payments, housing costs, school cost, pensions and retirement.
Let's say the vaccine gives cancer, AI diseases or sterilizes 1 in 1000 people and they die at 40 and the other 999 live life seemingly unaffected. Then the economy can continue fairly normally and the risk of my wife or husband dying on me is not really that significant. I would not be concerned about their vaccine status. It is a small risk and needs to be seen in light of other small risks. A vaxxed wife who drove safely or did not smoke cigarettes and had old parents and grandparents would be a better bet than an unvaxxed wife who drove carelessly or whose mother died of breast cancer.
1 in 100, I would be more concerned, but we are now getting into a national (perhaps global) situation where 3 million
additional Americans per year would die in their 30s 40s 50s, almost doubling the death rate. That is a political earthquake with major changes that would happen in terms of economy, lawsuits, political disruption. My future spouses willingness to leave the USA or move to Alaska might be more important than the 1 in 100 chance of them dying young. Alternatively the USA may pay families to have children and then a vaxxed wife from a large family who wanted 15 children may be a better catch than an unvaxxed women whose mother and sister were not able to have more than 2 children each.
1 in 10. Mad Max territory, completely unpredictable how life would look. I would probably marry any woman who could shoot straight.
