Are humans as simple as cars though? And why does sexuality get represented by the energy source n your analogy? Why doesn’t sexuality get represented by other characteristics? Perhaps because “there’s only two kinds - sedans and pickups” sounds a little silly?

It’s much more fundamental than that.

A better example would be how many axles a road vehicle can have to be considered a road vehicle.

You might reasonably conclude that the number starts at one and essentially goes to infinity and you’d be right.

But somewhere, deep in academia, some critical theorists are going to get upset that you’ve excluded zero and excluded the all the real numbers. They are going to call this oppression, and they’re going to invent a theory that says “actually vehicle axle identities exist on a spectrum that includes zero and all the real numbers, irrational numbers, etc.” if you give them long enough, they will also tell you if you don’t consider a vehicle whose axle count is an imaginary number, then you are imaginary axle-phobic.

Out here in the real world it’s very obvious that vehicles can’t have half an axle or 4.29 axles.

And the point is not because you want to exclude or oppress any road vehicles, it’s simply that being able to count the number of axles is a useful categorization for humans who work with road vehicles, so it has to be possible to say how many there are in an objective sense, in the real world.

Similarly, knowing which of the two sexes an individual belongs to does not tell you everything about that individual, but it definitely tells you a few things that are very useful in policy, law and custom.

It’s one thing for a man to put an a dress, it’s quite another for us to allow the law to consider that by putting on the dress he is now the weaker sex.

Yeah, I'm thinking you don't have much exposure to real world trucking and lift axles at all.

It's not uncommon for heavy load truck trailers to have axles that are only dropped to the road to take up a heavy load and are retracted for lighter and no loads to extend the lifetime of tyres and bearings.

Operationally, over their road time, the number of axles in contact with tarmac becomes fractional.

If you're going to make sweeping claims about "the real world" it's best to be across all those pesky actual edge cases.

The fictional speaker in quotes is supposed to be saying something silly, yes, and the "easy peasy" is to convey their overconfident naivete.
