His delivery of lines/speech pattern is also quite similar to Bashir’s too.I guess their line of argument is that he looks a lot like Alexander Siddig AND that he's wearing (a variation of) a Starfleet uniform (at first). I've seen people ranting "Bashir is a doctor and not a psychiatrist, these people HAVE NO IDEA ABOUT STAR TREK, WHO WRITES THIS CRAP". They will use literally ANYTHING to hate on the show. It's an obsession by now.
Maybe they can cast this character in the role of Doctor Bashir in a reboot of DS9? There is precedent for a white man playing a character of Middle Eastern origin, such as Benedict Cumberbatch playing Khan.
