KSA: =me
SL: Why do you think he is doing demonstrations? To convince people the thing works.
KSA: True, for the people he is trying to convince.
SL: So, the onus is on him to be convincing.
KSA: BUT NOT TO YOU! You aren't the center of the universe, or even a blip on his radar, I suspect. His need to be convincing TO YOU is a zero, just like you!

SL: If the amount of steam doesn't match the pressure he claims, if he overtly pours water out of a tube, if he is caught working the controls at exactly the same time that measurements change, then he isn't being convincing and it is perfectly legitimate to stand up and shout BS!
KSA: Go right ahead. It means nothing.
SL: If he ignores this perfectly legitimate reaction, doesn't try to explain, and just cries snake, then there are additional reasons to doubt him - ie, he isn't interested in being convincing (which would be easy), just in shutting you up.
KSA: You seem to think you are important. This, I doubt. You are probably LOWER than a snake on his scale.
SL: If the thing works, being convincing would be super easy.
KSA: But not necessarily wise. But that level of thought is beyond you since you are the all important center of the universe... (ha ha ha ... LOL, sorry, I just couldn't keep a straight face there anymore).
SL: Since it doesn't work, then being convincing is hard, except to convince those that are willing to be fooled.
KSA: Oh my, not only omni-important but omniscient too. Will wonders never cease! Worm.
