Where Do Jews and Christians on the Left Get Their Values?

I love this article because I have been stuggling with this question. I am still wondering how to help Christians (especially those in their 20's) that I care about see the contradictory beliefs of the left and the Bible. I feel like they are blinded to the truth and freely soaking in the lies that are being told. It is so frustrating to hear them talk about their leftist ideals when I know at their core they have conservative beliefs. Somehow they think their liberal ideals align with the Bible. Is there a good way to share with them without distancing them further??...
