But don't notice anything from that. That would be sexist, right Anton?
Second, yes, you are being sexist, and irrational. What you’re doing is exactly the same as the reasons that it’s racist and irrational to say “whites are better at x”.
You’re cherry picking data to examine, to reach a conclusion that you want to reach. You’re ignoring relevant causal factors - or any causal factors at all, in fact, aside from the spurious correlation you’ve assumed in your conclusion.
You’re ignoring decades of research on the subject - although in your defense, you’re probably just not aware of it.
Most irrationally of all, you’re generalizing across an entire group, selected by a factor that’s only indirectly relevant to the property you’re incorrectly generalizing about.
As such, “sexist” is just a symptom of fundamentally confused and under-informed thinking.
