I'm not everyone but it looks like you are feeding a troll to me. They are obviously being ridiculous, if they aren't a troll you are effectively punching a kid in the face for being dumb by continuing to engage with them. Nothing good is being accomplished for anyone involved either way.
However, the use of “lol” demonstrates that, just as in offline contexts, online users still feel the need to “save face” and avoid humiliation and disapproval when disclosing negative or critical thoughts and feelings.
