Sorry, supply-side Jesus taught us to only worship sociopathic corporations and leadership who act based on an unquenchable thirst for capital — so close to god they can't pass through the eye of a needle.
USPS is publicly funded and operated by a heavily unionised workforce — therefore the filthy proletarian communism of Lucifer himself.
Original is deleted, but I'm guessing they were ragging on the post office?
It's something of an outdated meme among libertarian types. The post office used to be terrible about losing things, and they became the poster child for wasteful government programs. They cleaned up a lot over the decades, but libertarians didn't get that memo, and now it's an anachronism hanging around their community.
