Honestly, no, I don't.
If they did, I'd get along with ENFPs much better than I do.
But of all the ENFPs I've known, very few have been able to connect with me (most make me feel very isolated socially, instead of making me feel connected with them), and about half of them have even been able to go so far as make me feel that ENFP are INFP without the sensitivity
I think that there's common ground, definitely.
The difference, though, is that where an INFP is a completely inwards-growing creature, an ENFP grows outward. So the "INFP" that the ENFP have mentioned really is just the xNFP common ground that the two types share.
ENFPs "inside" lack the complexity that an INFP has. ENFP are filled with the gooey xNFP material, but the material is much more dense inside INFP, and at the very center of it is a super-hard core.
It's like gas planets and terrestrial planets.
You guys have the massive personalities that draw people towards you, and it's an enviable trait. I just think it's a bit over-dramatic to say that what's inside of you is the same processes that we terrestrial planets are made of:
Terrestrial Planets:
Gas Planets:
At the end of the day, you guys are still 10x our size and can kick our asses. So what's the problem?
