Because both meanings are opposites
“really” -> “extremely” is not the opposite of “really” -> “factually”.
the literal use of literally is functionally lost
It isn’t functionally lost any more than “really” has become functionally lost. It’s contingent on context.
“It’s really hot outside” and “He’s really the murderer” have two very coherent and distinct interpretations.
In the same vein, “It’s literally as hot as the sun out here” and “This Christian extremists are taking the Bible too literally” have distinct and non-interchangeable meanings.
But the term has (ahem) LITERALLY been used as an intensifier since 1769. You’re far too late to the party on this debate. It’s LITERALLY been settled for centuries.





Same way people can wave a Confederate Flag 150 years after the war is over.
