Jade and Onpon,
A theory is not a fact, the very nature of a theory (scientific or otherwise)
is a conjecture, that most likely points to the truth but is as yet
unprovable, thereby it is not yet a fact. Reference the many "theories" that
are accepted as fact even though they remain theories.
A hypothesis precedes a theory and begins the investigation.
Nice try though.
One could also presume onpon that the refusal to investigate what the kernel
developers and others are upset about/concerned about, could make that person
a (to use your term) a "flat earth" proponent. It is the refusal or
unwillingness to investigate even accepted norms that leads one to folly.
