For too long, the level of frumkeit in the MO community has been purely watered down to accommodate their personal tayvos. Rather than living a life proper balance between intensive level beis medrish learning and intensive academia, the LWMO violate halacha whenever it is simply inconvenient to follow.
In co-ed high schools, the girls who keep shomer negia are harassed by teenaged boys,
and anyone who is more machmir than Jared & Ivanka with shmiras hamitzvos is written off as “Fanatically Kharedi.”
When young members of MO communities started frumming out after learning in OJ, Reishit, Gush, Shraga, and Mevaseret, their parents were extremely angry at their gadlus, so they started Open Orthodoxy to combat the influences of the Yeshivish velt & Rav Kook followers whose השפעה were causing LWMO to become more hostile to the silly tayvos of LWMO.
