Just yesterday, a woman wrote an article analyzing what she thought was a poor comic book cover, and she was met with just a bunch of shitty anonymous people being awful to her online.
I think that a huge problem is people who read comics and don't understand the point of superheroes, which is to be the best version of yourself.
You love Captain America? Well, you know what Captain America would never do? Go online anonymously and shit on a girl for having an opinion."
