Answer
Voodoo is a non-Christian religion that is incompatible with the Catholic faith, and the Catholic Church in Haiti does not tolerate voodoo.
It is no more fair for a Protestant missionary to go to Haiti and return declaring that the Catholic Church in Haiti condones voodoo than it would be for a Catholic missionary from Haiti to come to the U.S. and return declaring that the Protestant churches in America condone the New Age movement.
