This GREATLY depends on how one frames their own experiences, which we also do not get much information on from OP's post. If someone is merely seeking validation for their conclusions which they claim their experience points at conclusively, then they are FAR from the scientific method.
In fact, I'd argue the wording does point to such logistic fallacies. They cite their own experiences, not something more removed from subjective experience.
"The obvious issues I deal with..." are BY DEFINITION subjective. This person, and you yourself, are failing to understand the scientific method.
My point is they're NOT only getting incest and very niche things removed.
