Sim's exposition of the difference between Male Light and the Emotional Void is great stuff.

The only thing worth pointing out is that Sim didn't explain that if a Male Light is wavering, then it responds to someone else's (sexual) desire for that part of it which isn't Light, by becoming an Emotional Void.

And therefore, the 'Male Heart and Groin' is a falsehood of Sim's: having any sexual desire is not compatible with Male Light. It destroys others, and it destroys oneself.

If you reduce a person's intellectual strength to a biological organism, believing you can better grasp at their Light that way, you've made a case of mistaken identity.  Ideas cannot be better grasped by turning them into a bag of blood and guts, or a physical/emotional sensation.  Ideas are weakened, blurred and confused by feelings and intuitions.  The blind man gathers evidence by turning over the evidence in his mind, and he doesn't become absorbed in the sensations and sounds.

A model of Male Light, who indulges in compromise, and has Evil Eyes, treating those with weak, insecure, wavering Lights as Emotional Voids to satisfy the Emotional Void within himself, is the main source of temptation and confusion for those wretched souls.
