Thats a bit harsh
Wasps are never aggressive unless provoked IME. If they "attack" it's usually in response to a threat, very often some daft loon panicing and flapping at them
They can be a bit sleepy in the autumn which means that they're less able to avoid us as we clump about in our clumsy way and we're therefore more likely to give them a reason to defend themselves.
I react very badly to most bites and stings, but I know that wasps (and bees) will only harm me if I've already harmed them in some way. They're quite beautiful and fascinating things and it's a real shame that we tag them as sort sort of aggressive attack beast
