That's the opening line to Pride and Prejudice, where Jane Austen (I guess the "bot" part of the name is intentional) states something that many people of the time would superficially agree on, but which is intended to be highly ironic.

I guess the point of GP (and of Jane Austen) is that people never actually universally agree on anything. And when they superficially do, there is actually a large undercurrent of disagreement.

Another fun quote apropos here would be "I love standards, there are so many to choose from"
