But there is a reason for this.
The bible explains it.
They want to deny God.
And because only God accounts for absolutes, they are reduced to the absurd conclusion that they have to deny absolutes, even whilst they carry on using those absolutes, which they are denying.
So to be "right" in their rejection of God, they have to abandon logic, morality, uniformity and a sense of person.
And then they tell everyone else they are lacking in intelligence if they do not do the same...
I don't deny god, and if he shows up...he can have my place in line.
