However, apparently, if one goes along with such delusions, it is perverting the faculty of communication, which is contrary to natural law.

I don’t think it is what the Church ask us.
It is as if real people and real experiences are not really important, and all that matters are the scientific principles that can be learned from textbooks
real people and real experiences
are important. However we are all limited people and our experience is also limited. We can’t see all the dimension of everything by only empirical experience. If our experience is traumatic it can even distorsed our vision to life.
For eg, If a woman has been raped by a man and let her trauma run her life, she can quickly come to the conclusion that if one man treated her like that it is because she is undeserving. If this man was like that, it is because there is fundamentally something pervert in man’s nature. The only intellectual conclusion is to not procreate and let the human race extinct herself.
It can be seen caricatural, but I am sure that it is the thinking that some people see as rational.
That’s why we argue that experience is not enough and objective morality from God is to enlight our conscience.
Even most philosophs would agree that feelings are not enough and we should tend to something moral- an “universal” thruth for the human race.
