It's a stereotype because there are two things being considered synonymous or like.
Example of a faulty stereotype: Blondes are ____________ .
The two things are being seen as the same because of (mis)perception or misjudgment.
There's nothing mono about that, since they're two separate things rather than one.
First off...a "stereotype" (in the modern sense) is a prefabricated belief about something that eliminates the need for thought or observation. "Comparing two things" has nothing to do with it.
Second the "stereo" in "stereotype" has nothing to do with the number two. It derives from the French word "stere" meaning "fixed' or "permanent". Originally a "stereotype" was a metal plate used for printing that was etched with a picture or a block of written text that didnt need to be typeset letter by letter. From THAT meaning it drifted into the figurative meaning of a " preconceived belief about something".
So literally and ORIGINALLY (like four hundred years ago) a 'stereotype' meant 'fixed type', and not 'two' of anything.
However the modern usage of "stereo" to mean "achieving depth perception through two inputs" got started in the 19th century when folks starting looking through stereoscopes equipped with two pics of the same scene taken from different angles.
And then in the 20th century it got applied to recorded "stereophonic sound".
