That hilariously backfires on the maker, and you for reposting.
It calls a person an idiot. Singular. Yet it cites the plural "them" to make its point about a single person.
Additionally, it refers to person "lacking" math skills, when it means "lacks."
Maker also means "Adopts," not "Adopt."
And in last sentence refers to "them" for the definition of a singular "idiot."
Basically, the meme demonstrates that the maker is a moron at several levels. And that makes me laugh since the maker is calling out someone else (someones?) as an idiot.
