"This has no significant effect on the aeroplane", you said "Yes, rain will affect aerodynamic performance of any airfoil" - which is it?
There is quite a difference between specific airfoils (NACA 64-210 and 0012) tested in wind tunnel with simulated rain spray and real aeroplane flying through real rain. If one's agenda is panic-mongering through distorting the meaning of test results, well then disregard for the not so subtle difference is understandable.
Also, in my level 4 English there exists such a thing as insignificant effect so "it will affect" and "it has no significant effect" are not at all contradictory, but then I'm no native speaker and might be wrong.
Are you saying that Nasa also "has pretty bad reputation in scientific circles."?
No, but I'm saying that NASA's scientists never pretended their results could be applied immediately to real world unlike those who published their findings through
WASET that categorically claim:

OMG!
Them scientists found out the way to help pilots control the aeroplane in heavy rain and zee pilots don't care about it! Is the denial of industry there actually is a problem sign of worldwide conspiracy?

NACA 64-210? Certainly not laminar but probably more typical of early jets.
A UK AIB report mentions this phenomenon:
It's report on scud running that ended unsurprisingly. Rain effect is nice distraction.
I guess he meant "slip" when he wrote "crab".
