Regardless of my personal preferences (which is besides the point and I'm not about to defend myself), as sistermagpie pointed out, the al Ghuls have shown elitist behavior in the past, with Damian's elitist atttitude being the most recent example. Perhaps that is why my impression of Talia being like that has been reinforced. Furthermore, as I mentioned to a mod, Talia has in the past appeared very PICKY about who she INTERACTS with, and now I'm supposed to believe she'd "scratch an itch" with some no-name minion. People have also mentioned Bane as being from another world, but in his case, his strength & skill set that rivaled Batman put him in the warrior status that interested her father.
But hey, even so, Talia didn't like him and goes to show that not even that is enough to impress her. I dunno man, I can only suspend my disbelief so far.
