Throwing something new into the mix, what’s the official MO stance regarding Shem, Loshen and Malbush as being the reason Yidden were redeemed from Mitrzrayim even before they had the Torah? Among all the arguments about Halacha, this has been mostly glossed over here (some mentions of tznios, but only about women, not beards etc.).
Chasidim are obviously more “into these 3” but I believe one of the reasons for the high OTD rate among the MO (if true) is that they can blend in too easily into American culture so unfortunately many find it hard to “stand their ground” in Yiddishkeit. Being outwardly Jewish can be a matter of pride and even among weaker ones, be a reason to say for example, I can’t eat this, I’m Jewish and keep kosher, or at least be embarrassed enough to eat treif or openly desecrate Shabbos.
