Don't waste your time. No one can reason their way out of something they didnt reason their way into in the first place. A lot of people spent way more time than that individual thinking about what would appeal to the generic customer. And it so happens that regardless of gender, sexual preference, and pretty much anything else you can think of, humans prefer to look at human women and also prefer their voices over human men. And this is unlikely to change, ever, no matter how much they disagree with it, if history is anything to go by.
Let someone else swim against the tide if they feel like that's the best use of their time.
