a) I can’t choose for anybody else as these are decisions that are personal
b) Certainty itself is difficult and easily tricked. A great book for that is:
“On Being Certain: Believing You Are Right Even When You’re Not” by Robert A. Burton M.D.
c) I don’t have an issue with anybody choosing to utilize these arguments.
d) For myself: I refer to myself as “agnostic” as it is a socially acceptable term that can cover a range within which I fit. More precisely, you can add, I am “not atheist”.
e) Given these, that’s as far as I can think of right now.
