Well that’s true, but in this case I think it would fall under misinterpretation by the reader rather than accidentally racist. The main reason it needed to be deleted by a mod was because it was a picture of sexually active cats. No one wants to see that.
The text in the post was very clear - though it was not what Duracell was meant to actually post (confirmed in his latter post for clarity).
The picture of two cats at it is somewhat incidental and secondary to the text - though I agree in that no-one needs to see that.
Hence the deletion of the picture and editing of the text in his mis-post.
