Either by intent or accidentally writing in something that is perceived as malice so long as it is logically sound why that would cause problems. It is not logical as for why this would cause problems. People are just reaching far too much into it because either they are having the 'cannot separate fiction from reality' problem or they genuinely want to get rid of these types of writing scenarios. You might say that the emotional response is all that counts, but people get emotional over anything and everything. Logic has to take part. There needs to be validity for why it's offensive.
