If anyone who feels that way would like to suggest a neologism for the sort of discourse I describe, I'd be open to using it - I do feel the term 'scientific discourse' has been watered down a fair bit.
The issue is not that scientists, or discerning non-scientists, will take those views seriously, it's that others might (or will, or do). Hence the issue is not with defining scientific discourse, it's with educating a population to be able to apply that definition (or formulate their own functional individual ones).
