Yeah, because Jesus never hung out with sinners or anything.
Luke 6:37 - Jesus said "Do not judge, and you will not be judged. Do not condemn, and you will not be condemned. Forgive, and you will be forgiven."
Why do so many self-described Christians ignore the very basic things Jesus said?
It is the gospel of Paul and Roman aristocracy.
