Delusions make the human mind that more amazing

[Mozart Link]

First off, you would have no way of knowing for a fact if this innocent person's delusions would ever have negative consequences because any thought and such besides delusional beliefs (even scientific knowledge) might have negative consequences since science can be used for negative consequences. Since you would have no way of knowing, you should then admire and leave innocent people alone who have delusional fantasies just like you would admire and leave people who are scientists and atheists alone. But until this innocent person somehow decides to harm themselves and others and cause negative consequences (which might never happen), the happiness of these innocent people is the only thing that matters at this moment and not what others think of them and there would be no reason at all to tell them the truth of reality or try to convince them otherwise.

Nope, sorry dude, you don't get to equate people with identifiable delusions with scientists. And I'd like to live in a society that conducts itself and makes decisions using methods that are as close to realtiy as possible (since that's where we are). If someone has a delusion that informs their decision-making, and I would argue that most of our beliefs inform out actions in some way, I'm not going to wait until they do harm to themselves or someone else to speak up.

Explain how an innocent caring person would end up having negative consequences by having his/her delusions if the delusion is something without morals? I know that even innocent people with delusional beliefs in a God with the morals along with it would do something such as sacrifice others because they thought it was the right thing for God. But if you take away the morals and just have the delusional fantasy alone by itself, I do not see how there would be any negative consequences from it. For example, how would the delusional belief of there being heaven by itself without any morals have negative consequences if this belief is something that just brings this innocent person personal pleasure in life?
