The majority, not everyone, and that just means that the majority is wrong. Back in the days the majority thought that the Earth was plate, and the majority of the german voted for Hitler, just because the majority think something doesn't mean that that thing is right.
Let's take this part by part. In the MBTI, a Feeler is someone who put people over things, while a Thinker is someone who place things over people.
Here is what Meryl S says about this:
So, as she admits it herself, her natural preference goes for putting things over people, instead of putting people over things. Which means that Meryl S is a Thinker, not a Feeler.
So, if she is not a Feeler, she's not an INFJ, is she an INTJ, perhaps?
Perhaps, but actually, it doesn't work, because, as people who type her as an INFJ points it, she is an Fe user, not an Fi user, and even if their final typing is wrong, they are right about this. So if she's not an INTJ, she could be the Fe user and thinker counterpart, an INTP, maybe. But it doesn't work either, because we couyld hardly imagine an Fe-repressor, especially an INTP displaying such a smooth, sophisticaded Fe so easily, and this at every stage of her life, young or old. So, if she is not an Fe inferior, a tertiary Fe makes much more sense.
So, she is ESTP or ENTP. But she leans more on ESTP, because she never shows any difficulties to think and act in a concrete way, while she sometimes shows dificulties to think in the abstract or the symbolic. And she has also this in-charge interaction style, she is an Alpha Female, working the crowds with facility and grace, with a strong protocolar aura and an entrepreunarial, smooth operator style. Therefore she is ESTP, and by any means, she is certainly an EP, she is exuberant and fun, outgoing and versatile, and very engaging and open-minded.
So, she is ESTP, not INFJ. People identify her functions, but put them backwards.
Also, not everyone is stupid enough to type her as an INFJ, here is an in-depth article which thoroughly explains why she is an ESTP:
