Hmmm, I don't believe the Jesus portrayed in the bible was accepting of everyone. He was willing to forgive those who were willing to change. If a sinner decided to live a "life of sin", however, do you really think Jesus would just shrug and pat him or her on the head?
Forgiveness and tolerance are not the same thing. A church should be willing to forgive sin, but to ask it to tolerate sin simply because the sin has become acceptable to the non-believing community doesn't exactly make sense.
Again, I have to ask, how does a sin go from being punishable by death to being tacitly condoned by a church, and don't the fundies have a point in declaring such churches to be heading in a dangerously secular direction?
I'm obviously taking the devil's advocate position here, but I think it's a valid question nontheless.
