You seem to be looking to find grounds to criticize what I say, rather than first trying to understand it. This is leading you to creating strawmen - to the point that it begins to look deliberate. In case it's not, though, I'm going to try this one more time.
You are putting words in my mouth that I did not say, and I deny you the right to do so. Did I say "ever"? No. I said that, when talking to those outside the humanities, they should talk differently. (And what is the humanities if they only ever talk to themselves? Physics makes a difference to the world by what it enables us to do, so if the physicists talk only to themselves and to the engineers, they still can change the world. But if the humanities talk only to themselves, that's... not very helpful to society.)
And, despite me explaining it, you continue to misunderstand what I said about Feynmann. When talking to those who aren't at your level in the discipline, can you still make it understandable to them, without making them first have to get to your level? How far can you go to do so?
The problem that I see is that the humanities no longer seem to know how to talk to the culture at large. That's a real problem, because if the humanities are what they think they are, the larger culture needs them. The humanities need to talk to those outside the humanities, and to do so in a way that those outside can understand.
