THis is bizarre logic and self-serving nonsense you've been taught by pastors and Bible teachers, etc.Christianity scares you because it is inerrant and true. If it were not so, then it would not bother you.
Most of us who argue against your brand of immature, fundamentalist Christianity are not "scared"at all, but puzzled at the irrational silliness that you guys believe.
Just logically, why would something "scare us" if it is inerrant and true?
If Christianity WERE obviously inerrant and true, wouldn't it CONVERT us, effortlessly PERSUADE us, win everyone over? And yet it DOESN'T, does it? And the answer your pastors give you is "Oh, well, they're scared, that's why!"
You should go back and ask Pastor Billy Bob for a much better answer.:)
