If the argument is that

1) Feminism is a tradition of empathy and humanism 2) the application of OP's feminist ethos led OP to prioritize the needs of users in a particular way

You can argue that Feminism is indistinguishable from other sorts of ethos, but it'd be hard to argue that it's not an ethos at all.
