Just because you say you are something, or have experienced it does not make you an expert. I know that I personally get frustrated with people who use this expected authority to try to make certain things go their way. The book uses the example “Well, I’m a Catholic and so I ought to know that Catholic position on abortion.” When people make statements like this, is usually makes them look ignorant.
This is not the case 100 percent of the time, however. If the pope were to say this, I would be much more willing to accept it as the truth. He has earned his authority and his word is much more believable than a 15 year old who just wants to seem intelligent. Arguments like these have to have a good amount of kairos and come from the right person to be believable. I, personally, do not put too much weight on arguments based off a person's experiences unless the person is a trustworthy source that has proven them self repeatedly.
Most of the time shallow arguments made by people that do not know what they are talking about are easily refuted. A little bit of evidence, opposite of what they are arguing usually is enough to quiet them.
