I don’t think “female” is offensive.
I thought it was offensive because some (supposedly female) users said it was offensive; but I didn’t understand why my female friends used the term (female).
I found another saying that it wasn’t offensive, and I immediate copied that belief.
LGBTQ+ politics is confusing …
I have a feeling many younger feminists have done that intentionally, treating the word as a badge of honor for their vocalness in protesting. For the past 26 years, Portland, Oregon had a feminist zine with that exact title.
i believe the term is 3rd wave feminism
