I hate tumblr’s idea of ‘problematic’ characters so much.
An example of a problematic character would be a stock character of a marginalized group that’s reduced to a conglomeration of stereotypes that have a harmful effect on people from that group in the real world.
A problematic character is not a developed character with developed flaws and belief systems that people irl happen to be at odds with. It is not a character that interacts with other characters in ways that hurt them within the narrative. That’s what a story is. That’s what creating characters means. Developing a fleshed-out fictional person to serve a function within one’s narrative.
And characters that are solely mouthpieces for the creator’s own moral views and belief systems, regardless of what those views are, are bad characters, and make bad stories.
