Proof 22 from godisimaginary.com: 'count all the people God wants to murder'

• How should the 'God is imaginary' Proof 22 ('count all the people God wants to murder') be answered?

A host reads Proof 22 verbatim-ish from the website: Exodus 35:2 (Sabbath death penalty), Deuteronomy 21 (stubborn son stoned), Leviticus 20:13, the adultery statute, and Isaiah 48 ('the grass withers, the flower fades'). The site's thesis: these laws are insane, believers ignore them, and an all-powerful God would kill people himself — therefore God is imaginary.
