Agreed! On all points!

I mean, my father-in-law used to train Malinois for police work and SAR... are they inherently aggressive? No? Are they inherently able to be made aggressive with a higher propensity than some other breeds? Yes.

A lot of it has to do with activity drive. But most dog owners don't have time for that - and if you leave a dog with high activity drive to its own devices, it's going to find things to do - and those will be dog-centric and dog-oriented things... and funnily enough, that doesn't always line up with the kinds of behavior we humans want from our furry companions!
