Perhaps it is a contraction apostrophe. Example usage: “Dat moron’s dum”

It's true that the sentence could parse as written, but "moron's" would necessarily indicate the possessive, as in:

"Read the tweets, these schools can’t even teach the proper English of these morons."

Which doesn't make a whole lot of sense.

BTW, there's also a comma splice in there.
