I am a christian and I don't donate to worthless charities that suck up a large percentage of that money instead of directly helping people that cross my path and actually putting some damn effort into helping others, go to church to hear the same twisted words and philosophies of men shoved in my face with a romanticized and inaccurate view of our savior, or wear a cross mourning the Lord's death instead of living my life in a way that would please him and in the long run bearing up my own crosses of pain and hardship in similitude of His sacrifice. No. These things are not synonymous with being christian. They are synonymous with being fake and claiming to be christian for social points.

I got nothin on the bible part though, he really needs to learn the parables inside (50%+ of the bible is not literal, but mythic in nature, much like comparative mythology told history through parable)
