There is no such thing as a "genuine christian" anymore. Everyone has interpreted the bible and picked and chosen the bits they agree with according to their own moral compass anyway (thereby making the bible redundant), to the point where they have effectively created a new religion.

People will say "Yeah I'm a Christian, but I personally believe..." and then add all these qualifiers after it. No, you're not a Christian. Even priests preach with their own slant on things.
