I recently had some Mormons come knocking at my door, 2 absolute hot chicks (around 19-20, blonde, size 8 (american size 6), 5"5', well developed womanly curves, and not wearing too much - well it was a nice 29-30C, sun shining, etc). Anyway, it seems that to get new converts they were using the sex-sells angle. Fair enough...
So after chatting for 5 minutes at the front door (hey, I was after a phone number to take one of the chicks out, not converting to Mormon). I asked them both why that if under Mormon law, sex should only be between a husband and wife, why were they sending out 2 absolute stunners to lure guys in going the church (taking the sexy angle), wasn't that a contradiction to their own belief? And in doing so were playing with the devils wirely ways, and should repent.
Well, that went down like a bomb shell... These 2 young girls were so confused about the question that they had no answer, they tried changing the topic, but I kept pushing back to that angle... In the end, I think they got the message and left... (and no I didn't get a phone number).
Religion can be so fun sometimes!
PS. One guy I knew when I was serving the in Army, totally convinced another guy (who was a baptist) that Mary actually had an affair, and hence Jesus was born, not by immaculate conception, but out an act in breaking one of the 10 commandments! Because there no proof to the contrary and with everything we knew about science, how could that be wrong?
