What you are asking is if Lily was a completely different person would it be okay?
If Lily, a 19-year-old boy, was unaccountably not only a feminist, but was bursting with the need to help women. Who, despite being a 19-year-old boy, had a magical empathy with women, not through experience, but by osmosis.
If Lily’s entire life experience had been completely different to that of any other 19-year-old boy.
I suspect what you’re asking is if he wasn’t trans, it would it be okay?
Trying to separate out the layers of objection?
But, it’s more magical thinking. A man should not be holding position of a women’s officer.
Quite apart from the lack of experience, he’s taking the place of a woman.
And that’s not on.
