Oof. Such terrible analogies! Let's try talking about the thing itself in its own terms: The actual premise is, "the dictionary agrees with Steersman".
Methinks you're barking up the wrong tree, one that isn't even in the right forest. For one thing right out of the chute, you're mashing the definition and the examples into and under one umbrella term, i.e., "dictionary".
But the premise most certainly isn't "the dictionary agrees with Steersman", although your beef seems less with that supposed premise itself than with a supposed conclusion, which you've apparently pulled out of your nether regions, that "therefore Steersman's definition is the correct and widely used one." Though not quite sure how you think one or two examples refutes "widely-used", much less "correct"; one swallow doth not a spring make.
The primary premise is that, for example, the Lexico definition for "male" (below) is what is called an intensional definition, a concept which, as far as I recollect, virtually no one here has so much as genuflected in its direction despite my frequent reference to it. Wonder why that might be ... But, to wit:
male (adjective): Of or denoting the sex that produces gametes, especially spermatozoa, with which a female may be fertilized or inseminated to produce offspring.
https://www.lexico.com/definition/male
An intensional definition gives meaning to a term by specifying necessary and sufficient conditions for when the term should be used. In the case of nouns, this is equivalent to specifying the properties that an object needs to have in order to be counted as a referent of the term.
https://en.wikipedia.org/wiki/Extensional_and_intensional_definitions
IF that definition is, in fact, an intensional definition THEN it necessarily follows that "produces sperm with which a female may be fertilized" qualifies as that "necessary and sufficient condition" which ALL individuals - of ALL sexually reproducing species - MUST "have in order to be counted as referents of that term". No sperm, not a male. Q.E.D.
You MIGHT have something of beef by objecting that that definition doesn't actually qualify as an intensional one. Though you kind of have to then explain what OTHER traits might qualify individuals for members in that category - maybe transmen with their ersatz penises qualify? Maybe it's something one can "self-identify" as? Same things with "female"?

Methinks you're painting yourself into a tight corner.
But somewhat more importantly, you have to then argue that the concept of intensional definitions is null and void, that it has no relevance or bearing on examples that you might find a bit more "palatable" than the definitions for "male" and "female" - "bachelor" for example:
bachelor (noun): A man who is not and has never been married.
‘one of the country's most eligible bachelors’
https://www.lexico.com/definition/bachelor
So. Is that an intensional definition or not? Is "be a man who is not and has never been married" the "necessary and sufficient condition" to qualify as a bachelor or not? You maybe "think" that because I've found some million examples of people using "married bachelor" in a sentence that that somehow means that some bachelors are actually married? That you're going to try busting my chops if I say that I agree with that definition by pointing to those million (mis)uses?
For starters, a married bachelor is a married man who lives more of a bachelor life.

Sauce for the goose, sauce for the gander. The definitions themselves are trump; misuses generally count for diddly-squat.
But what makes the cheese more binding is that Lexico's (intensional) definitions for "male" and "female" are more or less exactly what biologists
stipulate they MEAN by those terms - see Wikipedia, Parker & Lehtonen, Griffiths, the Journals of
Molecular Human Reproduction and of
Theoretical Biology, along with a further cast of thousands of equally reputable sources saying the SAME thing:
https://en.wikipedia.org/wiki/Stipulative_definition
I'm STILL waiting for you to put your cards on the table, to show the same number of equally credible dictionaries, encyclopedias, and biological journals that provide similar intensional definitions for that structure-absent-function schlock of Hilton and Wright.
