As far as your comment that "half the burden of clear communication belongs to the hearer," that presupposes that the speaker is making sense in the first place. Let's put that to the test.
You're attempting to transform your silly original comment (post #7) into a serious-sounding economic argument; however, if you look at the overwhelming positive response that met the introduction of Boeing's more fuel-efficient 787, it would seem that you haven't got any point at all -- there is, in fact, a long-term economic advantage to fuel efficiency.
Your attempt to invoke "accountability to moral ramifications" is meaningless, since you haven't bothered to tell us precisely what the adverse moral impacts of fuel efficiency, quietness, or overall aviation "greenness" really are. One is left to speculate that your criterion is no more complicated than that you simply and unthinkingly hate the idea of "green."
I stopped reading here. I'm going to do be really generous and reply by pointing out that nohwere, ever, did I say anything about Boeing and its planes. I certainly implied the very opposite of what you have attributed to me --read: what you have imagined that I believe.
OK, one more favor: if you can identify what I did -- quite explicity -- take issue with, I will refrain from concluding that you answering imaginary posts.
