Why are atheists on R&S so agenda minded?

I don't think any one likes to be told that their whole Life is a Lie..This takes a lot of humility to acknowledge this. How many people do you know that would say this to your Face----I don't even know one. I don't even know of any Christians who would say this. Of course every one in my whole life that I have ever met minus about a dozen, have told me they were a Christian.I think this title gets used too loosely.
