If women don't support you in what you're doing it might be because they have been the target of unwelcome sexualisation at work themselves.
While I don't think they have the right to tell you that you are or aren't a feminist, insisting that women support you in what you're doing feels disingenuous too. Feeling that your actions might reinforce a wider problem, perhaps because of their own experiences, isn't "naïve" or "wrong"; it's just another point of view.
They might not even be labelling sexualisation "good or bad" or saying that it's empowering or degrading, but the concerns are -
- When we use sexualisation at work as women, we risk setting that as a norm, (possibly a standard) that men will expect from women in general.
- When that happens, as we've seen for decades, women are judged by their appearance etc rather than their expertise, knowledge and qualifications.
- Using sexualisation also makes it more difficult to call it out when men are doing it to belittle or dismiss us.
- Cherry-picking where and when sexualisation is ok is bound to result in differences of opinion between men and women, which can sometimes have serious or dangerous consequences (usually for the woman).
So no, not all women will support you in what you're doing and that's a personal choice.
