Some of the people who go OTD , go because they have no other option. They want to be relgious, but they dont want to be Charedi. for whatever reason. The men dont want to wear Peyos and a Beard and maybe the women want to drive.
By basically saying that more moderate versions of orthodoxt like MO are basically reform, you are totally chasing these people away.
One can be a frum man without Peyos and one could be a frum woman who drives , but according to some this is not the case and a slipperly slope ensures and they totally leave.
