I've never heard of anyone being beaten for just reading comics.
Everyone I knew growing up read comics at least occasionally.
Let's break this down even more.
Every one of the comic heroes that you have mentioned have been made into either TV series or movies previously. (Maybe not all of the Avengers,
Since the 50's, there have been movies, shorts, or TV series made about comic book heroes. Superman? Yes. Batman? Yes. Spiderman? Yes. Wonder Woman?
Yes. Incredible Hulk? Yes. These are NOT recent.
Help me understand. I think you were beaten up for more than just comics, dude.
These heroes are iconic. They were ALWAYS cool. You weren't reading comics before they were cool. You just read comics like everyone else.
I could go on, but I hope you get the point.
