Calm down.
Snyder's line is pretty clear: in his style of moviemaking, his vision of a "dark" superhero movie, a guy like Batman could get raped in prison. But, the idea of Batman getting raped in prison is significantly different from how Grant Morrison wrote Talia raping Batman. You're consistently trying to equate the two as if the're the same ("well Morrison wrote Batman getting raped, so what's the big deal if Snyder says Batman could get raped in his movies?") when they are completely different situations and, more importantly, with completely different reasonings behind those situations. Morrison's depiction of rape was a plot point to set up a larger story; Snyder's, more off-the-cuff, suggestion of rape is just to meant to be "look at how DARK and EDGY my shit can get."
Just because Batman was raped in the comics, and under completely different circumstances, does not make Snyder's idea of "Batman could get raped in prison in my kind of movies" any less juvenile or wrong-headed.

It's also something he didn't say.
