I think the person who posted this was placing the emphasis more on the comic at the bottom which calls out the unnecessary shittiness of the original tweet.

That’s not exactly ragebait, that’s more “someone said something shitty and this is why it’s shitty.”

It has a utility. Calling out shittiness is an important antidote against that type of shittiness. It’s like it builds people’s psychological antibodies, so when they encounter it in the wild they know not to take it seriously. They know they aren’t the only one’s who see through it.
