Certified stupidity will reign until we return to God.
Actually, per Romans 1 people may act this way because they first turned their backs to the Lord, refusing to retain knowledge of Him.
Certified stupidity etc is a potential consequence of apostasy. And it seems it is becoming a common consequence of apostasy, judging by the commonality of the fruit of depravity seen.
It’s like a big neon sign over their heads warning those who are or may yet be saved to flee from having fellowship with them, a sign given for the benefit of others to see and understand ... and not for themselves, those who are depraved.
To a big extent I reason that the knowledge that they rejected is that He is “Holy, Holy, Holy” ... and it has taken various forms too many people imagine are innocent like thinking that “good people go to heaven” which will lead to that many roads nonsense. The Holiness of the Lord is why sin is judged and why Christ had to endure mocking, scorn and the cross ... that He might bear the punishment of death for all those who will actually trust in Him (and we be imputed His righteousness), beginning with one of the two thieves.
But not the other.
