Ah. So it's the cynical manipulation one.
Cos I don't honestly believe that farmers are prejudiced as heck and their ability to manage animals for food supplies certainly suggests otherwise.
If you actually mean "male humans", "female humans etc., then right there you have my first argument for you actually being "reductive/false/prejudiced", because you'd be acknowledging that "male" and "female" only function meaningfully as qualifying adjectives, and we do indeed need nouns to describe the human variants - the human equivalents of "cow" and "bull".
Reductive - why shouldn't humans have these words too, in addition to other words, phrases, qualifiers and additives that describe the more expansive human experience?
False - where's the evidence that humans are sufficiently different not to have them?
Prejudiced - this is a justification for depriving the half of the human race uniquely disadvantaged by a physically weaker body of a word
And if you're saying that humans are too complex for this dichotomy to apply? Well, how the heck are we managing to reproduce?!
And if you're saying that it's the outliers that matter and which require the removal of these words? Well, I'm right back to "reductive, false and based on prejudice".
Reductive - because to say exceptions to a rule disprove the rule is to reduce language and meaningful categorisation to something unconvincingly arbitrary, while to say that exceptions render the rule unethical is to reduce the rights of those with a strong argument for retaining those words to describe themselves (an argument that is based on reason, evidence and judgement).
False - see, well... human existence?!
Prejudiced - see reductive.
