You've already acknowledged that a person with XY chromosomes can still be classified as a biological woman, so you obviously DON'T disagree.
To go by that standard it would be impossible to describe anything because there are always gonna be exceptions to the rule.
No, it just means that the descriptor you are using
doesn't rely on singular specific traits, but is instead more nuanced and complicated. Like practically all descriptors.
Just as it would be accurate to say humans have eyes that allow them to see colors, we recognize there are those born colorblind;
Right. But would it therefore be accurate to DEFINE a human as having the ability to see in colour in such a way as colourblind (or generally blind) people would not belong in that category? No. The only way around this, therefore, is to accept that while humans
often can see colour it is not necessarily a
defining trait of being a human.
but that is an exception to the rule.
Then why not do away with the rule and just accept that these descriptors only describe variable and non-exclusive traits?
We don’t define humans by the rare exceptions.
We don't define humans by any rigid definition that can exclude a huge number of humans.
Generally speaking, humans have eyes that allow us to see colors, and females have XX Chromosomes. Are there exceptions? Yes;
Therefore, it is accurate to say that it is true
generally speaking, but it is NOT accurate to say that those traits not existing in any individual or group DISQUALIFIES those people from being either human or female. So say that.
but those exceptions are deformities some humans suffer and a doctor can figure out what went wrong with the person to cause this deformity.
It doesn't matter. A human with deformities is still a human. A woman with deformities is still a woman. The point is not that there are exceptions, it's that those exceptions don't DISQUALIFY THEM FROM THE CATEGORY, so the category MUST mean something more than "humans can see colour" or "biological females have XX chromosomes". You have already acknowledged this, so you must therefore admit that the definitional approach to women as "having XX chromosomes" is simply untrue, even if you only admit that the exceptions are rare or "deformities". It still means that the CATEGORY is broader than the definition you are giving.
Rather than jumping through hoops to try and justify using a definition that is clearly and admittedly inaccurate, why not just adopt a more accurate definition?
