I don't know, seems like the whole "I'm right you're wrong" thing isn't working real well... how about let's try intelligence? 
 "Hi, I like Christianity, because of A,B, and C. It has helped me to 
learn about myself and the world and life in this way. I don't really 
know much about other religions though, there is so much to each one of 
them."
 "Oh hi! That's interesting! I like Judaism because of ...A,B,
 and C. It has help ed me to learn about myself, the world, and life in 
this way. I don't really know about other religions either, I have been 
focused on learning about Judaism. Let's exchange information!"
 
"Hello, I'm a Muslim, I like it because of A,B, and C. It has helped me 
to learn about myself, the world, and life in this way. I don't know 
about other religions either, I was born and raised into a Muslim family
 and we didn't really explore any other religion or belief in depth. 
Let's exchange information!"
 "Hi, I like Buddhism because of A, B 
and C. It has helped me to learn about myself, the world and life in 
this way. I have been surrounded by Buddhists mostly in my community so I
 don't know much about other philosophies or religions either. Let's 
exchange information!"
 "Hi, I don't like religion at all, it makes 
me feel like someone is trying to tell me to believe something that's 
not real, or that I don't understand, or that people are trying to 
control me. But I would like to hear what you all get out of it, why you
 don't dislike it, and what you have learned from it. And I will be glad
 to share my thoughts as well."
 (Doesn't seem very hard... just takes a little civility and self respect. Pretty sure that's what we're supposed to be doing in a free world anyway~)
