“Let’s agree to disagree” is a phrase being used around the country these days. It is the dialectic in short form. I just tell those who use such verbiage, including deceived Christians, to use that phrase on God on the day of judgment and just see how far they get with it.
Another response, for the here and now, can be, “Oh, I see, you’re one of those unprincipled people.” Anyone who uses the phrase “Let’s agree to disagree” is an unprincipled person since they do not have a position they wish to stand on except ambiguity and all they want is for you to become like them, unprincipled. If you agree to disagree with an unprincipled person you are simply justifying their ambiguity and are participating in the dialectic process yourself—kiss your faith good-bye.
