There's virtually nothing we can do about sexism in the media. One of the structural issues that I think we have is that the media continue to be dominated by elite white men. They may personally be lovely people, but in the aggregate they end up creating norms that are fairly distilled and don't serve a pluralistic society. For example, even in the coverage of things like sexual assault, we're still having debates about whether to write the word “rape” or the word “sex”. This is something that should have been finished 35 or 40 years ago.
When I think about sexism in the media, I think of it vertically. I think about everything from who is writing the tweet to who is writing the headline, to who is assigning stories, and to who is making editorial decisions. At every one of those stages, we can develop strategies, but no one strategy by itself is going to suffice. As far as I know, there are no laws for it.
