I'd be more specific that that: Attributing psychological motives or causes for another's religious views, values or theology.
A) Irrelevant - as to theology and exegesis in particular.
B) Slippery slope to reducing all religion to psychology - the atheist's toolbox
C) When well done rides very close to ad hominin, most often crosses over into 'you're nuts'
D) Non-rebuttable, non-discussion of theology; degrades into a psychological debate
E) Review your post I truncated; imagine someone doing the same using Calvinism.
Indeed - I can just imagine it happening right now.
But I've been forced to grow quite a lot spiritually from someone having the courage--actually quite a number of someones to have the courage to exhort me on the boundary of those two important parts of my life--spirituality and psychology.
Certainly there are hazards aplenty.
And I've been accused of being many foul things psychologically and otherwise by a whole raft of Calvinists hereon.
Last I checked, I was still breathing and God still loved me and even some Calvinists still care for me . . . so I think it's been quite worth it in terms of my own growing.
Why should I rob someone else of a similar benefit?
Of course, lots of discourses are really not intended for the faint-hearted, wimpy, wusses, thin skinned . . . including in the religion forum . . . especially in the religion forum?
LOL.
