Dear Avira,
I would venture that roughly a quarter of the YV is also not fastidious with tefillin, davening, or kashrus.
It really seems like you were never fully involved in a yeshivish community.
And how many Jews know all 13 Ikkarim in the first place?
The only difference is that MO is much more likely to be honest with their religious standing. Which is not intrinsically a bad thing.
