No, it's making fun of people who can't have a simple conversation without trying to discredit the other person by piling on an undue expectation of justification with regards to things that should be generally accepted fact and logic.

I can't be expected to write a research paper every time I make a statement. If the other party wasn't willing to google it themselves, then they were never going to change their mind in the first place.

I've quite literally been asked [citation needed] on the fact that people tend not to want to live in places where it's extremely hot or extremely cold. Asking that on trivially obvious facts is not any kind of good faith debate.

Edit: I forgot the most dumb [citation needed] I ever got: a guy asked for a citation that manufacturing a bike has less CO2 output than manufacturing a car. Just, like, fucking look at them side by side.
