I wrote the poem "De Feeneyismo - Iterum". My views and definition should be clear enough.
I'm not going to waste time discussing it here, or I'll get "pulled in" and that would be bad.
I must say, it was exhausting to see how many threads have been created over the years. I can't argue with such consistent demand for that topic. I don't understand it myself, but I shouldn't be subjective.
But what I can (and did) do is keep it all in one place. Some people can't stand the topic (for good reason!) and this addresses their legitimate complaints.
I'll leave you with the closing lines of the updated version --
So all you Catholics heed now what I say,
And strive to do God's holy will each day:
Take care of family, work and also pray,
and study well the errors of today!
Waste not your time and argue with your peers,
hawk Feeneyism like you work at Sears,
For if you take this path for twenty years,
On deathbed you will find yourself in tears!
