you won't be able to talk them out of it.

I know a guy who desperately wanted to go back to israel/palestine and I warned him that he was not prepared and had no clue what he was getting himself into. The guy was born jewish and then converted to christian but then decided to rock both religions simultaneously and he seriously believe that they(people in the middle east) would be impressed by his religious leanings.

  
He went over there and stayed with a 'trusted' host family, all set up through his church and as soon as he landed they forced him to give up all his money/valuables and then everyday they would make him get up and go to work with them, saying it was payment for rent(even tho he literally was forced to hand over thousands) the guy was so embarassed what was happening he didn't want to speak out and BARELY made it back home. they did everything they could to get him to miss his return flight and since they had all his money, he would have been SOL to get another ticket. thankfully he somehow tricked them and managed to escape.

he's never going back again and refuses to tell most people about the trip.
