Under-believer,
There are so many different people and personalities it's hard to say which is the best way to approach a dub with "logical" thoughts regarding their beliefs that simply make no sense. Depending on how long they've been in the org., they really aren't used to it (independant thinking remember?).
I've been pondering this myself for awhile, I have a sister that i'd like to help see the truth about the 'Truth'. Sometimes you just want slap 'em, (but that probably wouldn't go over well).
My ex-wife and I had a few 'discussions' about the same way after I DA'd and
before she filed for divorce.....
Me: "How are you going to explain going to our daughter's wedding (she's faded) when she's getting married in a church?"
Ex-wife: "Witnesses can do that".
Me: "Since when? And if that's true, WHY are you trying to TALK HER OUT OF getting married in the church that she's been baptized in, and REGULARLY ATTENDS??"
Ex-wife: "I'm not suppose to talk to you about spiritual matters!" She turns and walks away.....
