That's the exact opposite of what the link you included says.

From https://www.grammarphobia.com/blog/2012/12/beyond-the-pale.h...

As for the relationship between the two expressions, the OED has this to say:

“The theory that the origin of the phrase [‘beyond the pale’] relates to any of several specific regions, such as the area of Ireland formerly called the Pale … or the Pale of Settlement in Russia … is not supported by the early historical evidence and is likely to be a later rationalization.”

Also from the article: a “pale” is a fence. “Beyond the pale” used to require a suffix (e.g., “beyond the pale of reason”) but eventually by itself started to be short for “beyond the pale of acceptable behavior”.

And what were those fences specifically used for pray tell.

You have successfully repeated the opinion of the Oxford English Dictionary after reading an entire article about how the British used Pales to colonize areas and define boundaries, but I'm not sure it's as cut and dry as you want it to be.

Dude it was your source. Take the L and don't cite sources you haven't read going forward.
