"Let's agree on a common language before the discussion even begins."

It's hard enough for scientists even in the same field to agree on definitions/meaning of terms: context conflicts can easily occur between disciplines.

But when the totally uneducated/ignorant with a faith based drum to beat, waltz in and stomp all over a discussion where they are, from their manner and words, clearly out of their depth, and refuse to educate themselves into the context because their infallible invisible magic sky fairy uses the terms in an incompatible different way, they throw abuse around and put down those goddam stupid scientists... well it's at least laughable.

And they wonder why they get ridiculed, or ignored....
