Why is the rest of the world sick and tired of American christians..?

I am a Christian, only 14, and I know what's going on this world. Maybe not every detail, and i typically dont inform myself of the stars lives, becase i dont beleive it is my business to know what famous persons dating who, and whos getting a devorce this week. I find learning up on them is a waste, but i know much about whats going on. Just becase im a christian DOSNT make me uninformed and ignorant. Im sure there are uniformed and ignorant christians. But there are also some uninformed and ignorant athiests. Dont be so steriotypical. God Bless!
