You could have googled that; but I suspect it's a rhetorical Q. In other religions? Yes. In defense of the veracity and reality of comic book superheroes, though? I'd have to say no. In view of that, I continue to assert that the atheist's use of the spiderman analogy is spurious and of no value.
Then you concede that the "But people died for their belief!"-argument is invalid and/or not compelling?
