Vochindik: How about you define this “MO” that you think is so problematic? I will grant you that a “Modern Orthodox bungalow colony” that has established mixed swimming (should such a thing exist; which I actually doubt) is not really Orthodox. But that shouldn’t reflect on “Modern Orthodoxy” as a movement. If I would start a “Chareidi bungalow colony” with mixed dancing and mixed swimming, would that mean that people shouldn’t be “Chareidi”? No. It would just mean that I misappropriated a name. So too here.
There seems to be a widespread belief that “Modern Orthodoxy” and “Torah Judaism” are far from the same thing. It’s an idiotic assumption. The actual “Modern Orthodox” have the same Mesorah and Halachah that everyone who thinks of themselves as “Torah Jews” do.
