Re: Alexander Siddig Interview: He reveals anger over changes to Bashi
Genetic enhancement is illegal in the Federation, so he had good reason to keep quiet about it, even to his closest friends (who also happened to be in Starfleet). While you and I might not consider it particularly shameful, it's something that hurt Bashir deeply going back to his childhood. I think he kept quiet about it also because he was trying to forget about the whole thing. I don't think he was putting on an act as much as he was simply in denial about it. He wanted to be treated as a normal human being, so that's how he handled himself. He had moved on, and here he was forced to face it again which is the last thing he wanted to do. That was what I took away from it.
As did I. I don't think he was trying to deceive anyone as much as he was trying to distance himself from what happened. His parents were the ones who decided to have the re-sequencing done. Once Bashir learned the truth about his background (while in high school), he did everything he could to separate himself from what they'd done to him. That he stopped calling himself "Jules" as opposed to "Julian" is a nice way of illustrating how he felt about his past.
