I think he is an INTP. Yes I think he is quite emotional, but I don’t think that’s the reason you doubt his type do you? You probably have to mention those points.
I see Fe in him quite a bit which might make others think he isn’t one. But I see that in ALL INTPs except for jockthemotie and stigmata. You see you can SEE your Fi at most occasions. Some Fi user said they can view their feelings as if it’s a person standing in the room with them. Although that’s obviously an exaggeration – I think – I get the picture there. It’s obviously because it’s your first two functions. Dom and Aux people can see. It does not mean you can control them and make sound decisions devoid of being overwhelmed by them but atleast you can view them.
(Infact I think most people spend most times thinking about their second function more than the fist. The dom is your default, you don’t even think about it. This doesn’t belong here of course.)
Now think about an IXTJ. They have plenty of Fi. They just don’t see it. They can’t negotiate on it. - I do understand Fi can’t be negotiated on but FPs have a bit more understanding of it so as to know when it’s influenzing them. It’s easier if you know about MBTI of course -. This is why IXTJs are so stubborn and undending at times. They always always tend to think that they are always right too and my goodness, teen IXTJs are the worst. Do you remember that kid (fireshield) who had a crush on a girl that he had a hard time expressing feelings for? He had a long freaking blog. He will never ever ever take advice from ANYONE although it’s obvious he is wrong. That’s Fi influenzing him without making him known.
Likewise, INTPs have Fe as their untapped feeling function. And negativities of this function affect them quite a bit without making them known. So they think they are being rational at all times but if that Fe fucks them up here and there without informing them and they don’t see it. Others might, they don’t. And how dare others say that they are being emotional, it’s obvious for the INTP that feelings don’t influence their decisions – so they think.
But then again you know all ^. So it might be some other reason you think he isn’t an INTP e5. You’ll have to point them out though.
But for me he is an INTP unless someone points out something I haven’t been seeing all this time.
