It's ridiculous, I don't know if those comics have inappropriate or outdated themes and elements, it's not a reason to remove or censor them. Sure, some things in older publications can be offensive for someone, but aware readers should know that's because they were made in different times or it's just plot element. Especially some controversial symbole like swastika shouldn't be removed if they are there just for story reasons and they aren't glorified or anything. I mean, if I remember correctly, in one of those comics Predator was just killing nazis, how it is supposed to be offensive or controversial? And even if it was, there shouldn't be any prohibition to take up uncomfortable topics in popculture works, as long as they aren't specifficly and purpously attacking someone.
