Well the people you encountered were probably lukewarm christians i.e not true followers of God. The type that are christian in name only no faith.
My personal rebuttal would be this verse from mark mark chapter 7:18-20
"And he saith unto them, Are ye so without understanding also? Do ye not perceive, that whatsoever thing from without entereth into the man, it cannot defile him; 19Because it entereth not into his heart, but into the belly, and goeth out into the draught, purging all meats? 20And he said, That which cometh out of the man, that defileth the man."
