Ok, so I just looked my description up on that second link Loop posted, and I feel much better. LOL!
That one describes me fairly well, with a few nuances.
Also, I meant to highlight this line from the Keirsey explanation of a ENFP:
With a dramatic flair, they share their experiences with others, hoping to reveal some universal truth or win others over in support of a cause.
Now come on, y'all... you KNOW that's totally me! LOL!!! Though you probably never realized it (unless you know me offline), that underlined part is especially true of me... I'm always trying to collect data to come to some universal truth so I can put it in a box and move on to the next subject... 
LOL! Wow. You and Bishop2 are the exact same type! I can definitely agree with that!
Ever since I got that
ENTP result, I 've been looking at different descriptions on the internet, and that one definitely describes me! The original ISTP result just didn't seem to quite fit. I'm probably like you, LaRue: 50/50 Introvert/Extrovert because though I can be the "life of the party" and can be VERY outgoing at times and don't mind being in a crowd, I'm perfectly fine with being alone and sometimes don't want to be bothered with the folks! Also sometimes in group settings, I'm the one that's quiet and not saying much, doing more listening than talking.
Also, aside from the love of arguing/debating, this sentence really jumped out at me as well:
"
ENTPs have little patience with those they consider wrongheaded or unintelligent, and show little restraint in demonstrating this."
OMG that is SO me! All day long! Also this:
"
ENTPs are basically optimists, but in spite of this (perhaps because of it?), they tend to become extremely petulant about small setbacks and inconveniences. (Major setbacks they tend to regard as challenges, and tackle with determination.)"
This is so true as well. Any time a major setback comes, though I get kinda stressed, I'm usually the one remaining calm and viewing it as just a "bump in the road" that I'll get over, and I ALWAYS think I'll come out on top, and I usually do!
And this:
"
They tend to have a perverse sense of humor as well, and enjoy playing devil's advocate. They sometimes confuse, even inadvertently hurt, those who don't understand or accept the concept of argument as a sport."
OMG! How many times right here on LGM has someone gotten a little offended with me because they think I'm berating them with my arguments, and they think I'm mad and trying to insult them because I can get pretty passionate with my arguments! That is TOO funny!
And I'm ALWAYS playing the devil's advocate! Also, at times my sense of humor tends to sometimes be biting, sarcastic and sometimes "wry". My friends accuse me of having a "slick mouth" because of some of the one-liners I have uttered!
Finally:
"
They highly value knowledge, and spend much of their lives seeking a higher understanding."
That is SOOOOO true, and it's one of the reasons I decided to pursue a career as a teacher!
This is all too interesting to me, which is another trait. I'm very interested in who I am.
