I suppose it depends on one's views on whether that is an injustice in the first place, and then if one thinks it is the responsibility of TV producers and writers to fix it.

Should it be the role of software engineers to fix social injustice as well? Perhaps our designs should be subject to review by some committee to ensure they meet certain criteria, as would likely be the case with The television industry if you wanted to ensure compliance.

Mass media usually trails, rather than leads, on these kinds of things. There were tons of gay parents before you saw any on tv shows as recurring characters, and they still insist on the stereotype of the nerdy male engineer. Unless you think those are good things, it seems like they should work to stay at least current.
