You see, Christians aren't meant to be judgmental or have profiling questions. All they need to really do is talk about their experiences to anyone willing to listen. Maybe share a verse or two. But most importantly, listen to people who are willing to be open to them, and to not judge them. Then let God do all the work. And if it doesn't workout, just move along.
As an athiest it's sad to have so many on my side try and attack christianity. I have met alot of good christians including my Grandfather. He was one of the nicest and most caring people i have gotten to know.
O.O
