The saddest quote is this one from Andrew Greely:

I often regret that I ever became engaged in this area of scholarly investigation. It has been a waste of time. Doctrinaire slogans, conventional wisdom, shallow ideology, pessimism, and nonsense have dominated the discussion of Catholic education for so long that I have little hope that mere findings, no matter how solid, will be taken seriously. Certainly my own work and that of the research heritage I have described has had no impact at all.
