I am surprised the figure from is so high. At least Pew research is able to grasp that Catholics are Christians. But given that a lot of people, including most libtards and climate alarmists, think it’s unsophisticated to be Christian, the figure is reassuring in an amoral age. It’s also reasonable to assume that many of the half-educated, half-smart iconoclasts who flaunt their half-baked opinions and who describe themselves as atheist or agnostic, are still at heart adherents of some Christian values and beliefs. They think it’s clever to deny the existence of God.
On the other hand maybe a lot of these ‘white Christians’ are Mexican mestizos who also believe in Quetzalcoatl.
