I'm meeting more and more of this type of person: it's as though their inner person (soul?) has been hijacked and they no longer have the capacity for self-reflection/examination. They are like empty husks; it's all about external appearances and mindless virtue signalling coupled to an unshakeable belief in their moral superiority. Reminds me of this Bible verse:
"If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal."
1 Cor 13:1
