There are a lot of reasons to point out media that fail this or that marginalized group. The euphemism “problematic” acknowledges media that traffic in stereotypes, show gut-wrenching physical or emotional violence for shock value, discuss the mere existence of marginalized groups as though it were funny enough to be the punchline of jokes, or otherwise promote the deadly ideals of kyriarchy. It’s largely a matter of public record that it’s not really possible to totally eschew “problematic” media. Our ability to even recognize things as problematic is dependent on the axes of oppression of which we’re aware, so one person’s seemingly innocent pleasure is another’s dehumanization-for-entertainment. Additionally, many problematic tropes are so entirely because they are pervasive, dominating depictions of members of the groups in question, rather than because they are directly insulting or damaging, and so can only be redeemed by other depictions becoming common enough to offset their impact.
There’s something that gets lost in discussions of problematic media, however, and that’s how they can be a necessary stepping stone for people on their way to better things.
