I think the problem is not "the preaching work" JWs did not invent preaching. Infact most churches preach hench why they have preachers. It is also not a lack of "love" JWs are not aliens. The problem is in reality most JWs peolple have problems with are not very social and are basically like street gangs in the hall. If you are not in their gang they'll beat the crap out you, or if fortunate they'll totaly ignore you. THe titles don't help either. You'll be suprise about the insane "acts of love" you will never hear about because the you weren't "in the club". I mean I've found out insane things after they happend and wonder why either we were not told until it was almost over, and you are stuck looking like a callous idiot, or johny come lately.
I think another thing no matter how you put it there are some things jws can't do with a straight face. THey know it is wrong or stupid, and you are the new person. So it is like they are selling you a used car. "Its just a lil rust" I think so many people are replused not by the religion its self but by the uneasy stalemate JWs put them through.
A:"I love your faith can I be one of you guys?"
B: "Well you'll have to believe the moon is made of cheese, and then drink gutter water."
A: "But the moon is not made of cheese and gutter water is disgusting cant I join you religion anyway?"
B: "Well no you can't until you concede to drinking gutter water, and believing in cheese moon."
A: "But that has nothing to do with 99% of your religion, and it is just stupid. Well what if I just worship with you guys with out joining, can't I still benefit from it"
B: "Well yes but we will make you feel guilty for benefiting from us with out joining us every meeting"
