'more or less' is not recognized

Michael Loucks

In the following excerpt, PWA suggests replacing 'less' with 'fewer' missing that it is part of the phrase 'more or less'.
"I know of one case that worked out to be permanent, and it more or less mirrors what happened with your dad. He wouldn’t be granted permission to marry in the church, nor have his secular marriage crowned, except with extreme repentance and after a long period of regular attendance at services and spiritual counseling.”
