At most, it implies that "more men than women generally do ______," which is totally true. Even that implication would be a bit of a leap were it not for parent's later explicit clarifications on the point.
Above, did I imply something about tall people's abilities to reach items on very high shelves? I didn't claim anything about tall people specifically. But I think I did make a claim about their abilities here, by implication, given the context. It's natural to infer the claim - this is just part of how people communicate. The claim is strongly implied - tall people can reach items on very high shelves.
I believe OP's clarified claim (of people in AP CS classes, most are men; of people at summer coding camps, most are men; etc), rather than OP's initial claim (most men take AP CS classes; etc). The clarified claim seems accurate. The initial claim is clearly inaccurate - and OP "stand[s] by it 100%".
It feels like we're dancing around the issue. There's no reason for this line of thought to have continued like it has. "My side" should have made a polite comment, and when rebuffed, thought "they don't think it's a problem," and moved on. "Your side" should have thought "a slight rephrase could increase clarity and address their concerns." Instead we're just pointlessly banging our heads against a wall.
As is, both sides of this argument are actually pretty stupid. Mine included.
Good point, thanks for introducing some sanity.
