Devil’s Advocate, I don’t really agree with the idea that there is an equality between observance of Shabbos and sitting in BEsi MEdrash and learning (notwithstanding the fact that we DO say that Talmud Torah K’neged Kulam). The frum velt really needs to take off its blinders and recognize that sitting a learning Gemarah is NOT for everybody. Everyone has different intellectual strengths, temperaments, and patience, and not all guys are cut out for the type of learning that we usually think of when we say “Sitting and learning.” That is a far cry from saying, “not cut out for Shabbos.”
This young man clearly is committed to OBSERVANCE of the Torah, if not the actual formal learning of it. Maybe he goes to a Shabbos shiur (or would) or likes to go over the parsha with the help of Artscroll. Maybe he would enjoy reading English language books about Halacha or Hashkafa. These are all forms of learning. I know a lot of frum men who rarely open a sefer. But they keep Shabbos in every detail, they are kosher to the letter, their wives all go to the Mikveh, and they are raising a generation of kids who are all in Yeshivah.
We really need to stop stereotyping what is frum and what is not. NOT all guys are cut out to sit and learn, and they are honest enough to admit it, yet they are committed to Yiddishkeit. That says a lot to me. There are lots of guys doing little more than warming the bench in the Beis Medrash, who ought not be there. So are they more desirable as an asset to their sisters’ shidduchim?
