Akup – wow, yiddishkeit being reduced to 3 mitzvos and a piece pf fabric on your head really caught me by surprise.
Yes, MO generally keep those things, except a study in 2015 by an MO group found that not even 3/4 of MO people consistently wear tefilin, practice taharas mishpacha, and keep shabbos fully, nor do they believe fully that Hashem runs the world and that the Torah is 100% true.
But even without that study, you’re accusing the Torah world of also just keeping those things.
What about mitzvos like not touching women, including relatives? lo sasuru? Tznius? Bitul torah? Reading lashon hora and apikorsus? Checking for shatnez? Not taking jews to court? There are a ton of mitzvos that are practically hefker in large parts of MO
