It’s literally an observation of the content of the comic. Fuck me, you people are stupid.
Stupidity is a cancer in our society. It deserves ridicule and scorn, not niceties. Note, this is different from ignorance. There is nothing to be ignorant about here, just piss poor reading comprehension and disregard of context clues. Shameful.
If it helps, and you probably aren’t aware, but we are ridiculing you.
But it doesn’t seem to be fixing anything.
