My inclination with you is young INTJ. Especially with your posting pattern.
In both the video threads you started and your response to the ENTP Christians thread you made some very brash, irrational conclusions and then backed up those conclusions with a very black and white sense of logic. Ok, well let me rephrase, you seem to have a Te view of what is logical (lots of "because of x and y, z must be true). You also seem to have Ni's sense of conviction and conspiracy.
You have a theory created by Ni (that a video is funny and requires a developed sense of humour to "get") that you back up with logic (so if you don't "get" it then you must not have a developed sense of humour). There's nothing wrong with your logic, per se, but it's trying to back up a conviction that makes a lot of assumptions. I know a number of INTJs who are convinced about something that they have had insight about and believe to be true (Ni + Fi) and then reason the hell out of it (Te). They make sound logical arguments for their case, but their logic is based on the assumption that what they believe is true to begin with. Until they prove that what they believe is true to begin with, whatever argument they make afterward is moot. They can come across as pedantic and close-minded if they're not careful. "Because I said so" does not make something true. Nor does repeating your conviction over and over again.
Anyway, you also seem to have a sense of us here "owing" you the time of day to figure out your type. Unhealthy Fi (or perhaps Fi that hasn't quite been developed enough yet, which could be your case seeing as you're only 15) can manifest itself as a sense of entitlement ("me against the world" mentality).
Good luck and maybe try not to be such an irritating asshole. I know you're young but it's never too early to start improving.
