You never have to apologize for expressing an opinion.
It should be pointed out that inductive and capacitive loads affect current flow, capacitors cause time delays, and inductive loads cause forward and reverse EMF. Both cause the imbalance in current flow on the hot and common and can cause GFCI's to trip. A hair dryer is a combination of resistive load (the heater) and inductive load (the blower motor). That is what trips the GFCI not and overload. All GFCI receptacles that I have seen, although configured as 15 amp outlets, are designed to carry 20 amp, that is expressed as the pass through current rating of the unit.
