Unfortunately that means you are a hypocrite, but at least you accept and acknowledge it. Does the church not make a stance that if you see something bad and don't do anything about it be a sin as well as the act that is going on? If that is the case, you cannot have dinner with me because you know about me and have a "duty" to teach me the proper path.
Err ... not really. Let me quote some scripture. Back then a tax collector was like ... umm ... someone really bad. Maybe put pedophile in there. And a pharisee was an expert on the scripture and a worker in the temple, very much like a pastor.
Mark 2:13-18
The Calling of Levi
13Once again Jesus went out beside the lake. A large crowd came to him, and he began to teach them. 14As he walked along, he saw Levi son of Alphaeus sitting at the tax collector's booth. "Follow me," Jesus told him, and Levi got up and followed him.
15While Jesus was having dinner at Levi's house, many tax collectors and sinners were eating with him and his disciples, for there were many who followed him. 16When the teachers of the law who were Pharisees saw him eating with the sinners and tax collectors, they asked his disciples: "Why does he eat with tax collectors and sinners?"
17On hearing this, Jesus said to them, "It is not the healthy who need a doctor, but the sick. I have not come to call the righteous, but sinners."

Hebrews 12:1
1Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles, and let us run with perseverance the race marked out for us.

Obviously this is a low-level runthrough but I have to be in class in 10 mins
The model provided by Jesus for what to do with people you beleive are lost is not just to call them on it. There is a time and place for telling people you beleive they are wrong but the general commandment is that we are live above reproach, "a city on a hill cannot be hidden" -- the process is supposed to be that the non-beleiving see something different in us and begin to seek it.
