“OO might identify with MO, but MO doesnt identify with OO”
That is not true on the most part.
Regardless, of the OO, Charlie Hall wanted to insist that R Gordimer is not Modern Orthodox because he does not agree with many of Charlie’s definitions of MO (OO), and therefore it is inappropriate for R Gordimer to have written the article.
Which is just an inane proposition. R Gordimer is clearly identified as a MO rRabbi. He has smicha from what is the premier, if not only, MO Organization that issues smicha in the US. He is an executive member of the largest MO rabbinical board.
I guess the comments were too pointed for some and they therefore wanted to come up with some reason to ignore his message.
