ENFPs can seem ENTP and vice versa, just ask Aleksei or Orobas.
It's not about how you act in the world, it's about your internal world. You cannot mistake being Fi dom or aux when you experience it from the inside.
A lot of feelers (correctly or incorrectly) think of themselves in the colloquial sense as 'rational, even-tempered, logical'. Lots of INFPs are in computer science/programming and INFJs are notoriously rational.
Typology is not about the 'colloquial sense', it's about cognitive functions.
In a crude way, it's not about 'how intellectual/objective/logical' are you - but how XYZ are you in relation with your Fi? Many ENTPs on the forum at least will tell you that they don't really 'get' Fi, other than as a concept.
Fi is how you experience the world in a psychic, gut-reaction way, almost primal way not how you filter it and act in the world.
Also, other ENFPs on the forum will tell you themselves that their level of Ti and/or Te really varies.
It's pretty normal for feelers to get annoyed by
other people's emotionality. You see it on the forum as well as real life. Being a feeler doesn't necessarily make you adept at handling or appreciating other people's emo.
Just offering another perspective.
