I do think that beyond "let's burn this all down", there's at least some discussion to be had on the topic in general. Hell I never would have even questioned my basic assumption up there if we weren't talking about this. I think things like this need to be discussed, and discussion isn't necessarily the same as a witch hunt.
In Discord we were discussing "problematic" representation by a person in the minority doing the representing. Like, how with trans stuff for example, there's kind of this policing of how other trans people can write about themselves in fiction and such. I personally think that you should be able to write about your own understanding of your experience however you want, but I think that there are enough bad actors as far as just dudes who are doing fetishy lesbian stuff that there are people who will side-eye if they don't know you.
Like, I think that's just a natural reaction. If I see someone playing an over the top black thug character, tossing around the N word and binging buckets of KFC and being the biggest caricature, I'm gonna very deeply question if this is even remotely an actual black person, and I think there are people who will be uncomfortable with it.
So yeah, it's a fine and complex line. What if this person is an actual black person, what then?
I don't have a clear cut answer for you (beyond not throwing around the N word, which I said pages ago), but I believe that it's important to realize that these discussions are nuanced and it's important to accept and embrace the concept of nuance. Some discussions are just that, a discussion. They don't always have an easy solution or answer, and discussing them is how you get a better understanding of how to navigate these difficult situations.
