First of all It Seems to me his comments are insulting to his former fellow Anglican priests who are married and doing a responsible ministry and to all married Protestant ministers who are well respected and considered to be doing a good job with their churches. Granted they probably don't play as much golf as the celibate Catholic clergy.
I see how it could seem such, however this article was written for a Catholic publication that is read (pretty much universally) by Catholics.
I think if he were writing for some other publication...such as Touchstone he would have written it differently, like for instance pointing out the common custom of daily Liturgy in the Latin Rite of the Catholic Church. Which from what I understand is on the rarer among faith traditions. As most others traditions limit services to Sundays and holy days.
