To the extent that the essay is seen as a weapon it simply elicits a rebuttal weapon. Ordinary catholics and ordinary evangelicals can and mostly do get along. We catholics, of all people, know how we are "used" by leadership for ideological purposes. 
As the awed child noted as he viewed the morass of excrement: there's gotta be a pony in there somewhere. For starters, we are largely referring to elitist ideologues who:
-are smart,
-entertain hidden aims that are shared secretely, 
-shun real uaccounability for ideology or leadership 
-pander to gain, satisfy, keep followers
-manipulate and use "simple" followers for these hidden aims.
-will throw anyone - even children - under the bus to hide, preserve, further.... 
We "ordinary sheep" need to watch the "fight" together, listen and learn what we really should reject: gurus of hate, ideologues, radical fundamentalists, whether they be Catholic, Protestants, Jew, Mulsem, Evangelical, atheist...
Think, talk about what we should embrace.
