The temptation is to appease- to retreat with apologies. Certainly scripture doesn't tell us to go around judging the behavior of non-Christians and loudly proclaiming how sinful they are or how righteous we are. That just isn't the example set forth in scripture. We are to do everything in love, live our lives in a manner that is pleasing to our Lord, and do our best to serve as a faithful ambassador for Christ in our times and in our place.
I admit the tone on both sides of this issue is unsettling. These societal trends are disturbing, and I wonder what is the best way for the body of Christ to respond to it. We must never call sin anything other than what it is, but Colossians 4:5-6 tells us, "Walk in wisdom toward those who are outside, redeeming the time. Let your speech always be with grace, seasoned with salt, that you may know how you ought to answer each one."
