I'm not so bothered about his having a difficult and not likeable personality.. because I get and agree with your point about geniuses being the weird, difficult and unlikeable personalities.   

My problem with Wright is the seemingly forced nature of this whole matter.  His behavior is not logical in respect to someone who may really and truly have been Satoshi... and it is just not my pie in the sky vision of the matter but instead more substantive of an impression of his forced phoniness.

The more that a person is directly exposed to some of his words and videographic statements, the more repulsive it becomes to attempt to give any benefit of the doubt to the guy.. and even Gavin for seeming to go along with it.

The below two articles seem to lend some additional buttressing of my inclinations.

Here, even Gavin seems to be having second thoughts about giving credence to Wright.  In fact, looks like Gavin may be back peddling from his own attempts at scamming and having had been discovered to even exercise such bad judgement.

O.k..... We did not get to meet David Kleiman, but really Kleiman's kind of personality and quirkiness seems to be much more in line with a potential Satoshi... to the extent that it may matter who is Satoshi...   And, yeah, if Kleiman was Satoshi, then there may be some kind of question regarding whether there is any way to get at bitcoins that may have potentially been in his control at or near the time of his death in 2013.
