I highly doubt the INTj - too wanna-be obnoxious, negative and certainly too much pointless talk (how much more non-INTj can it get, people! Look at how other INTjs here write! In addition, I don't know ANY INTjs in real life who are this pretentiously obnoxious and I know a few).

But ISTps are not obnoxious, so I doubt UPD is ISTp.

ENTp is my guess.
