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~)
