SJS: you didn’t read my rhetorical question.
Of course, the yetzer hara is an equal opportunity yetzer.
You missed the whole last part of “why go OTD if your theology claims it’s permissible to be over aveiros within the framework of “MO”?” Note the part about “your theology claims it’s permissible to be over aveiros”. This dubious distinction belongs to MO, not traditional orthodoxy. Traditional orthodoxy rightly holds that it is forbidden to do all aveiros, even ones that conflict with secular culture and we don’t really like.
So since you mentioned skirts, there might be some Traditional Orthodox women who have their struggles with Tznius. But they don’t claim they are better than those who do adhere faithfully to Tznius. Whereas MO holds you can just do what you want (obviously, even MO has their limits, but those limits are already well outside normative orthodox Judaism).
Here is your quote that Rabbi JBS said MO is a horaas shaah (at best). Mishpacha Magazine seems to have had an article on Rabbi JBS.
On another site, regarding that Mishpacha article, the following is part of a comment posted there.
[but]
Note also the part about “This secular culture entails destructive elements, many negative and perverse aspects; it may be a blessing and a curse simultaneously, and thus AS LONG AS ONE CAN LIVE WITHOUT IT SO MUCH THE BETTER FOR THE SPIRIT”.
This doesn’t sound like something anybody should *want* to be a part of. If you (foolishly) claim there is no other way, then you are simply denying reality.
While there may be flaws in lots of “systems”, that doesn’t excuse abrogating halacha, CH”V, which clearly, and proudly, happens in MO, even if they feel they that modernity permits them to do so. What you posit amounts to “I can proudly violate the Torah because their system is flawed”. I would not agree that this is a Torah approach.
