There are many things you cannot do if your judgement is impaired.
You can't operate a motor vehicle.
You can't be in charge of children.
You can't operate machinery.
You can't legally do anything that is dangerous or will endanger you or anyone else.
And it isn't limited to a current state. Background checks are made to see if you have a history of being impaired that result in being denied jobs or access to certain people, places, and travel.
Having a clear SANE mind is essential to functioning.
Why do we allow people that obviously have impaired judgement vote, teach, hold office and other important even dangerous jobs?
If you believe in any conspiracy theory without a shred of evidence is impaired judgement. It illustrates the lack of judgement, the lack to think critically and logically.
Believing in a deity is impaired judgement.

For example, if a law enforcement officer just started arresting people because he/she guessed that the individuals they arrested would commit a crime sometime in the future, we would naturally consider that person mentally unfit to serve in that capacity. He/she might even shoot someone on a whim rather than having any factual justification to do so.

God believers, conspiracy theorists are no different. They only have a guess that there is a god, yet they impose laws, brainwash children, even arrest people based on that guess.
They vote for people that take that "leap of faith" to operate civic offices that rule over our lives.
Society should take a long look at this situation and come up with a sane and solid plan to prevent people with impaired judgement from having any control over the society.
