Why Can't Jehovah's Witnesses Say 'Hi' to Disfellowshipped Jehovah's Witnesses?

. But none of our religions forbid us from continuing to be friends. Personal friendships don't end when someone finds a new church. We just don't talk about spiritual matters. EXACTLY. Other religions let their members do whatever they want even if it is against Bible teaching as long as its member keep putting the money in the coffers. Christians are supposed to be guided by the Bible. Not the other way around. Did Jesus tell us not to talk about religion? Did he and the Apostles refuse to talk about religion because it may cause an argument? So called "Christians" will do anything and condone anything to keep from rocking the boat. What is the purpose of being a Christian if you do not obey God's laws?
