There are many more articles, but here's a simple one.

"This article was great because it really dispels the myth that RAW can
fix
everything; the camera literally captures differently depending on its
white
balance setting."

You, like many others, erroneously assume RAW data is just that, 100%
unprocessed data from the sensor, it is not.  WB is calculated into
setting
many different camera parameters, even simple ones such as how the camera
exposes an image.  True, you can always change this is post, but at a
cost.
Set you WB so you can intentionally blow your blue channel and come back
and
tell what you find after you correct it in post.  You get more leeway with
RAW than using JPG, but you are still not getting a free lunch shooting
RAW.
That is why it is so im****tant to get it right in-camera.
