When people are full of hate, going to talk to them, hugging and such and trying to get to know them on a personal level simply does not work. Jesus may not have had a "sign," but He SURELY told all He spoke to REPENT! And, He spoke far more about hell in His ministry than He did heaven.
Not sure where you get the hugging thing from or why you think part of the message of speaking with people doesn't include the message to repent. It can include that just with a different approach. Some people NEED for people to take the time to understand them, or at least try too.
And if someone doesn't want to receive your message, what did Jesus say to the disciples? Shake the dust from your feet and keep moving (obviously to find those who will)
