When someone is trying to communicate some stuff to an audience, it's the responsibility of the orator to ensure the audience understands what they're trying to communicate, it's not the responsibility of the audience to figure out what the orator means thru their own effort or research or whatever.

There's always a baseline expectation of some kind of shared context, sure, and within that kind of context your comment makes total sense. But all of the stuff I'm pointing out is definitely not part of any notion of that kind of shared context. That's my whole point!

If you give a lecture to 100 people, and 5 people leave that lecture confused, that's their problem. But if 95 people leave that lecture confused, that's your problem.
