Uh ok.Yeah, I lean more strongly towards ESFJ than ESTJ (because she seems to thrive on Fe), but I see nothing but ESxJ in her. She was known for being an over-achieving, hard-working, hyper-involved child with a knack for public speaking. She has even said herself that she attributes her success to early ambition and a belief in hard work and dilligence. Moreover, she is quite infamous for her nit-picking, detail-mongering ways (as well as for her megalomania, but I don't think that's type-related.)
All of this taken together points way more to ESFJ than ENFJ. Unless of course you think that her belief in some conspiracy theories or the character she played in The Color Purple are more typologically relevant than the things I listed. Oh, and before anyone does it, I'll just go ahead and say that if you attempt to say that the characteristics I listed in favor of ESFJ can be equally applied to ENFJ, then you are guilty (as many on this site are) of stealing the standout traits of SJs and giving them to Ns for no other reason than that you are stubbornly stuck, for whatever fucked-up reason, on calling her an N.
For the record, I do not type people based on some sort of sensor quota system. If it seems that way, it's simply because there is, not a tendency, but more like a rule in this subforum that everybody is a goddamn N of some sort. You'd think that, given the accepted statistical proportions of types ("SJs rule the world, boo fucking hoo me"), someone will have noticed the ridiculousness of this behavior. And, admittedly, many have noticed, but the rule remains. I type Ns as Ns when they display characteristics of their type. It's much more work (and much more confusing, not to mention theoretically scattered and inconsistent) to rationalize someone's type using stupid little meaningless details. That's when I know it's become less about discovering someone's actual type and more about rationalizing one's own type because they want to be N (they think, "well if I'm an INFP and I have these traits, and person X also has these traits, then person X must be INFP too. She can't be ISFJ, because then that might mean I'm ISFJ, and that's simply not possible.)
