But we can’t pretend we’ve lived in a world of equal opportunity that treats men and women, males and females, equally
in trying to make that point.
While I agree with the first part, that is not implied or necessary to refute the argument as presented.
They argued the same reasoning applies to "male" (literally). It clearly doesn't.
Therefore, whatever the reasoning could be, their argument isn't it. Basic logic.
If a sound argument exists, we should present that. Otherwise, we're pretending to reason.
And a nonsignificant amount don't. That doesn't establish a generally accepted convention of the language community.
True: still not a conventional definition per earlier remarks.
Exactly: convention.
Incomplete evidence or composition fallacy.
Nope, not implied & it's not about my use, either. It's about observed, established convention: see earlier remarks (notice a pattern yet?). The lack of consistency across usages indicates that derogatory meaning is not a convention.
And plenty of innocuous instances exist as discussed before. That doesn't make a word itself derogatory:
I don't deny derogatory instances. Do you deny nonderogatory instances?
It's simple overgeneralization: people can draw wrong conclusions about their observations, especially if they disregard conflicting observations (incomplete evidence fallacy). Observing derogatory uses while disregarding nonderogatory uses doesn't justify any conclusion about a word's conventional definition.
It varies by message, so it's not the word itself.
Straw man fallacy. Not implied.
Maybe you follow the logic I wrote, but the conclusion still feels wrong, so you're unwilling to accept it. Let's unpack that feeling.
The conventional definition that the noun "female" isn't derogatory feels wrong, because sexists use that word in an ugly way, and opposing that would feel relieving. What can we do with these feelings? Here's one idea: even though it's not generally accepted, let's make the noun "female" an official dirty word. Let's accept the premise of their sexism that "females" are lesser and take it further than they did: spread it to the broader community, normalize it into the official language so everyone accepts the noun for an entire gender is a dirty word. The sexists might even be grateful.
Would that feel better? If so, then extraterrestrial anthropologists studying you might reasonably conclude you're a misogynist. Otherwise, you might want to tell your feelings "Fuck you, feelings! Stop making me do stupid shit!". Alternatively, understand your feelings & guide them better.
