I feel a sort of kindred spirit thing with every NP that I meet. An Fi/Te commonality wouldn't be any more viable in my opinion than an Ne/Si commonality. All NP's "speak the same language" - meaning their primary mode of extroverting is Ne. I usually click with them right away. Even if they go off on some crazy Ne rant that I don't feel like listening to, I at least understand it and feel a "sameness" with them. With NJ's, it sometimes takes me a long time to determine if they're even N's or not.
I TOTALLY AGREE WITH THIS. Though I can clash with NTPs when they're in heavy Ti mode, I sometimes feel really understood by certain ENTPs, especially, because we're both Ne doms. There's an "openness" or something there than Ni doms don't have, even though I share Fi/Te with INTJs. I feel sometimes like ENTPs are more similar to me in how they kind of can shift, adjust, let things go, forgive and forget, whatever.
Same thing with SFJs. I think the fact that I share Si/Ne with them can be enough of a connectin because I have so much Si ...but ONLY IF they have a lot of Ne development. Smart SFJs with a lot of Ne I can actually click with in this way I can't explain, even though they don't like discussing theory as much as me, or telling me I'm being too general or something.
People of any types can get along. I felt a really intense connection once with an ENTJ male IRL, and I sometimes feel like certain ENTJ women on-line are almost ENFP-ish.
The people I think I have the biggest clashes with are STPs and ESTJs, and I feel repressed by some ISTJs, but also like them in a way, it depends on the individual.
Oh I should probably tack on here that I can feel a strong similarity with certain SFPs, too. ShortnSweet, an ESFP on this site, really seems ...I don't know, like she says things I want to say or agree with a lot. And I do have some qualities I share with my ESFP mother.
