What causes a person to go insane, nuts, crazy?
What is insanity? Simply put: It is believing in lies.

Causes:
Not accepting a person for what they are.
Continually stopping, blocking them from expression and being themselves.
Changing the subject midstream during the conversation.
Laughing at, making a joke when a person is talking about a serious subject.
Minimizing, invalidating and not allowing the person to experience their own feelings and
thoughts.
Denying physical needs, requirements or desires.
Physically assault, harm, steal, destroy or torture the person's body, belongings or people or pets they love.
Forcing the person to do things against their will, either overtly or covertly.
Insisting they stop being who and what they are, instead attempt to force or convince
the person they should change to suit someone else's desires and fit in with the common status quo.
Bullying with constant criticism, degradation, threats, mocking, humiliation.
Comparing them to another person and to the vague "everyone else" .
Setting up competition with false ideas and delusions
that one is better than the other, that there can only be one winner therefore everyone else is a loser.

Based on fear, doubt, skepticism, hate and lies the insecure push and promote
their false beliefs upon others and transfer their insanity to the world.
Victims of the insane are labelled as insane after they have endured lengthy
brainwashing while the truly insane wear a false mask of sanity in public.
