Many people DO address it. Just because you don't see something you're not even looking for, doesn't mean it is nonexistent. Many people call out idiots like this (hell I'm doing it now).
And no, you are objectively wrong in blaming the religion in any way for people saying crazy things like this. It's like saying a large billion dollar corporation at fault because one lowly employee (not even remotely close to exec or anything of the like, I mean a low ranking near minimum wage employee) says something racist. It's absolutely ignorant as all hell to say "welp, that whole company must be racist" when he doesn't speak for even 0.001% of the company, let alone the policies the company instills in the employees to follow.
It's not even worth reasoning with you if you are that willingly ignorant. Not even just religion, you have to be incredibly unintelligent on multiple levels to say that makes any amount of sense.
