mistletoe,
Theme park fortune tellers are there to entertain. Nothing more or less. These days, predicting at least one divorce does not take any extraordinary powers...one just needs to know the statistics.
I do believe that there is wisdom available through psychic experiences, but not from theme park fortune tellers. I don't believe a belief in psychic phenomena has anything to do with whether one is Christian or non. But I know that some Christians believe it against their beliefs to believe in psychics
