I'm sorry you feel that way about Christians, and the Christian faith.
I'm sorry you have met so many Christians that are bigoted, self righteous and intolerant people. I too have met Christians like that. I can easily say that they are not easy people to be around, and therefore I stay away from them. That is my choice.
However, even though I am a Christian I have lots of fun. Every day is filled with fun and joy. Not rules and legality. (that is not fun)
I find it fun to treat my neighbor with respect and love, It is fun to NOT murder, lie, cheat, steal - it is fun to be living morally right. Because then, you don't live with and guilt or circumstance that arises from immoral living.
ff, Ichiro, Uncas and Nick5: if you and I were neighbors you might be surprised because I wouldn't treat you any differently than one of my Christian friends. Meaning you would be treated with the same respect and love. No bigotry involved.
It's much easier to love than to hate. It is much easier to see positive things than negative things in life. It is much easier to forgive than to hold grudges. (healthier too)
I have many friends and family members that are NOT Christians. We get along just fine. There is no contest going on where we are trying to convert each other or be self righteous. We respect each other and have thriving friendships.
It's a shame that so many people have violated Christianity down through the ages. It sure makes it hard on every one else that lives according to the Gospel of Jesus Christ.
