You cannot be good friends without respect for each others beliefs, be they religious or otherwise. I am Christian and I have friends from other religions. We often discuss our beliefs and agree to disagree. Most religious differences stem, not from the individual, but, instead, from what the individuals have been taught. Sometimes, my friends and I review the differences in our cultural norms and we can each understand how the other's belief system developed. If two people are truly friends, then one would not want to force another to believe what he/she believes. In addition, if an opened mind is maintained within this friendship, the differences can, possibly, offer opportunity for spiritual growth. In our society, the unspoken belief about differences amongst individuals is that a source of conflict is created because of them. My belief is that conflict is created by our reactions to what we believe. Therefore, if we can react as friends and be willing to listen, conflict will succumb to knowledge.
