There exists one blog Authentic Judaism on the far right spectrum that lately has been attacking Mishpacha magazine . He has not given explicit examples yet as to what he finds so objectionable, other than mentioning one columnist whom he feels gives a negative slant towards a Kollel lifestyle.
I have heard similar murmurings in the past when Mishpacha printed material that was considered negative towards Chabad. I heard the same when Mishpacha printed material that was pro Chabad.
All in all, my opinion is that there is no way to please everybody. No matter what you print, someone will find it objectionable. It is up to every parent to decide what literature to bring into their home. Mishpacha broadens the horizons of its readers. For those who prefer to remain insular, please petition the Agudah to resuscitate the Jewish Observer.
