the physical therapist had a misconception of what feminism is, probably due to conservative misinformation that presents egalitarian movements like feminism as forcing men and women to be treated the same, and in this case the PT thought this meant soldiers were being forced to have women on their units that would slow them down or make them less effective because they weren't allowed to vary the tasks based on strength because of "feminism". I'm not even sure her story was based in reality, tbh - I'm not sure whether the military integrates women soldiers that way, but either way she has internalized some griping from her husband about this.
Either way, it's interesting to me you wouldn't identify as a feminist even if you agree with feminism - I wonder what connotations it has, and how those connotations will change if people who are feminists don't own that ... That was part of why I owned being a feminist in my interaction with the PT - she clearly had a misunderstanding of what feminism is, so I clarified why I see myself as a feminist. Otherwise she might not ever be challenged in her views, and "feminism" just becomes the absurd strawman she rejects.
