Sushe: Pashtus is no one created or founded Modern Orthodoxy. It was just a different way of reacting to all the terrible losses Yiddishkeit suffered during the Haskalah. The Chasam Sofer’s Derech was to negatively prevent people from leaving by cutting off those still frum from the rest of the world. The other Derech was to embrace the world and positively keep people from leaving by having Frum Jews associate with the rest of the world and see why Judaism is still better than them (I am using the words positive and negative in their literal, and not colloquial, senses). Both have worked for different communities and both have roots in Yiddishkeit going back over a thousand years. There is no real other difference between “Modern” Orthodoxy and “Traditional” Orthodoxy, as some here like to call it.
