I think that's still insufficient.

I'm a feminist, and we should put all women in prison

cannot be coherently asserted, but

I believe murderers are agents who should be treated accordingly, and put in prison

can be coherently asserted, so it cannot be the idea that we should treat women as agents that is generating the contradiction. You also need some additional premises about women being agents with certain moral properties. Equally,

I'm a feminist, and women are all stupid

cannot be coherently asserted, but

I believe stupid people are agents who should be treated as such, and that they are all stupid

can be coherently asserted, so it cannot be the belief that women are agents and deserving of appropriate treatment that is generating the contradiction.
