Religious Tourists like these should most certainly be kept out.
This from the BBC website:
//The charity, which Ms Silsby incorporated in Idaho in November last year, says it is "dedicated to rescuing, loving and caring for orphaned, abandoned and impoverished Haitian and Dominican children, demonstrating God's love and helping each child find healing, hope, joy and new life in Christ".//
And this extract from the group's planning document is also included on the BBC website:
//Given the urgent needs from this earthquake, God has laid upon our hearts the need to go now versus waiting until the permanent facility is built. He has provided an interim solution in nearby Cabarete, where we will be leasing a 45-room hotel and converting it into an orphanage until the building is complete. //
I suspect that rather than trying to rescue orphans from the earthquake zone, these people were more interested in rescuing them from the influences of Voodoo, so in reply to Everton's question, I would say their religion is very relevant to the story.
