Christians(and probably religious people in general) fall into 3 categories:
1. The nutcases who believe in every single word in their holy texts.
2. The people who just pick and choose at random what they like from the texts(they believe in the "main story", though).
3. The people who admit that it's all bullshit, but that there is some wisdom and good messages to be found and thus they still define themselves as Christian.
Number 1 can't be reasoned with, but luckily they are rare.
Number 2 is the most common and the most annoying overall. And, in a way, just as stupid number 1.
Number 3 are not really Christians, but they call themselves that for whatever reason(probably social pressure).
Now that I've dropped a bomb: see you later, gonna eat dinner and watch a movie
