I am pretty sure no one here said this, or even implied it.
Again, "for all intents and purposes" was the phrase, and that covers a lot of ground.
My few examples were pregnancy and menstruation (although even then, not 100% - but you see my point I hope).
While the phrase does cover a lot of ground, I would suggest it also be subjective.
Imagine you have to choose between to objects, A and B. For 99.999% of the population, their "all intents and purposes" with regard those machines are satisfied by both. Would it not be correct for them to say "for all intents and purposes, they are indistinguishable"?
But, aha, there are one or two functions that are of significant importance to 0.001% of the population, and here object A is capable, while object B is not. That 0.001% of the population would presumably then go "for all intents and purposes, they are not indistinguishable".
To me, both of these are correct, but they depend on what one sees as "all intents and purposes". It doesn't literally mean "all intents and purposes regardless of context", but is an idiom to mean something more akin to "in all
important ways". It is inherently subjective phrase. Now, often the context is obvious and everyone might be on the same page as to what is important or not.
But, given its subjective nature, when one argues that A is not indistinguishable from B, one is giving away what they see as important use-cases for the objects in question. So, if you see pregnancy as an important use-case that is lacking in one and not the other, that would seem to speak to your "important" use-case when you see objects A and B. Menstruation? Is that really one of your "important" functionalities with regard a woman?
I'm being flippant, of course, but the point is there.
The difference would seem, therefore, to be that Billvon sees object B as being, for all
his intents and purposes - i.e. what he sees as being important functionalities - as being indistinguishable to object A. Whereas you, JamesR, would seem to see, what? Pregnancy and menstruation and a number of other functions as being of important?
To put it more bluntly, presumably Billvon doesn't see the important function of women he meets to be naked, to be able to get pregnant, to menstruate etc.
Just saying.
