OK, I'm not understanding this.
Your mother read the descriptions, took the "tests" and self-typed as ENFJ YET, everyone else is saying she's not. Evidently, the woman isn't entitled to know herself as well as anonymous folks on a website.
I admit, I have very low tolerance for people typing others as ESFJ on this forum based on primarily negative characteristics...I believe someone used "micromanaging" as proof positive she's an ESFJ?
Tater, if you wanted to talk about is there a God, etc I'd exit the conversation ASAP and start talking about the latest celebrity gossip. I have zero interest in discussing such matters. I find topics like that to be the McDonald's of "abstract topics." Novice, easy and convenient, almost rote but you get quick abstract points for participating. To me, they're psuedo-abstract along the lines of "If a tree falls in the woods and there's no one around..." As far as the abstract topics are concerned, I'd try seeing what her interests her abstracting them and seeing how she responds. It seems to me that people are focusing on topics of interest to them and if the other person isn't enthralled, then they're not deep enough.
I also notice that both you and Pitseleh still live at home. I find that a lot of the "defining" ESFJ characteristics tend to come from those who are still dependent on the ESFJ in their life for some reason and are not pleased with the situation. Many of the complaints are like she (typically she) is always focused on cleaning, or something like that. I'm not trivializing legitimate family problems, but I find it hard to take people complaining fairly typical parent-child relationships seriously. If I knew about MBTI when I was a teen, I'm sure my mother would be frontrunner for the most evil ESFJ ever.
