If you want to engage in a conversation or use that information, yes you should properly read it. What could possibly be added to a discussion otherwise? Just having people have to correct and call out your bullshit? Lmfao.
Since you are engaging in comments within a post about this, everyone would assume you read the graph properly, since you obviously can’t add to a conversation without actually knowing the information.
So yes, leave your idiocy elsewhere next time, read the shit, or don’t add your opinion, really simple concept.
