Where are 'grim' and 'existentialist' in those? Not that MBTI is a theory to base anything substantial off of, because it isn't, but I don't see anything matching those adjectives. It's also worth noting that ESFJs are depicted as in need of a
structured environment, which should theoretically make them correlate more to a Socionics extroverted rational type than anything else.
Just my two cents. I don't wish to offend your personal Fi understanding. It just doesn't correlate with my personal Ti understanding.
