In John 4:23 Jesus says to the pagan woman at the well, "For the time is coming woman, indeed is now here, when you will worship not on this mountain nor in Jerusalem but in truth and spirit."
She had 'seven husbands and truly none' and would have been considered unclean trash to Jews like Jesus, yet he chose to share one of his deepest and most important truths with her, not with the Pharisees.
So if he chose to do that, I figure present day Christians could choose to adopt an attitude of respect and hope towards everyone, regardless of their religious beliefs, gender, sexuality, or social class.
In other words, worship in truth and spirit. Share your faith by showing your kindness, respect, and openness.
That's how I see it anyway.
