Do you agree with 'leaflet preaching' on the street?

I recently had a woman give me a letter/leaflet... she was just trying to give them to anybody that walked past. I found this rather odd and I thought 'doesn't she have anything better to do?' Anyway I decided to challenge her a bit about what was in the leaflet... I said why do you believe a book that was written by me in the middle ages but she just spouted out verses of that book to me, she didn't answer my question. Also to all those that say IQ isn't correlated with religion, she seemed to have some sort of mental health issue.
