He can only be either ENTp, ESTj, or ISTp ...
As for whether he is ENTp and ISTp ...
ENTps and ISTps can think alot alike and have many many similarities, those of you who are ENTp and ISTp and have experienced semi-dual relations can testify to the fact that they are alot alike in behaviour, mannerisms, and the way that they think. Hence, possibly the reason why there is so much confusion on the board over whether he seems more ENTp or ISTp.
However, there are things about him that do not seem to reflect to me that he could entirely be an ENTp. I am saying this mostly from the fact that I am 100% sure now that I am an ENTp, and the way I relate to Rocky has not seemed exactly like the way I have related to other ENTps ...
So, I am going to make the proposal that if Rocky is an ENTp, then I am not an ENTp ... Because I do not feel that he is totally ENTp.
