He has nowhere near enough data points to justify a comment describing
"all" charter pilots.

Do you not need more data points to dispute it?


No. To support a blanket generalization, one needs to survey the entire
population. To refute a blanket generalization, one need only survey a
single member of the population, so long as that member is a
counter-example.

I wouldn't say the entire population, but I would want a sample size
that gives me at least a 95% confidence level! :-)
