The tame US comic still does not pass all 41 points of 1954 comic code which was fully endorsed. Nor half "Disnified" cartoons and stories for little children.

It is pretty much impossible to defend comic code as written, even ignoring the argument that adults should be able to read horror stories (including those grittier then Game of Thrones) if they like them. Comic code was simply a reaction of people unable to suddenly process that many have different preferences then them.
