You are talking three different things. Peace, love and salvation.
Christianity talks and believes in peace and love. But as far as salvation goes, Christians believe that Christ is the only way for salvation. As non-Christians, if it gets your goat, tell the Chrisitian to get lost, since he is offending you. If he still offends you, if I were you I would probably paste a duct tape on his mouth.
AND
it would do you a world of good to take time out of your busy schedule and read Discovery of India.
