So you can't imagine any scenario where a young, vulnerable person, who has never experienced any sexual desire, would benefit from simply being able to say 'Sorry, I'm asexual' to someone keen to initiate a sexual relationship with them? Rather than struggling to find the language to turn them down?
And you can't imagine any scenario where the young person hearing that, easily recognises and understands that because they have more awareness of asexuality due to increased visibility, and they take no offence to being turned down accordingly?
In the complex teenage world of social pressures, awkward, imperfect communication, coercion and blurred boundaries of sexual consent that lead young people into sexual situations they later regret, you can't imagine any scenario where this language, and this awareness might be helpful?
I would call that a dramatic failure of the imagination, personally.
