You are so whacky a person that this took genuine effort to determine whether or not it’s satire. I know when you typed that up it probably seemed hard hitting and effective, but I’m just imagining someone earnestly saying “You don’t know anything.” as an OPENER and I cannot stop laughing about it.

To me it’s the same as people opening with “No.” and then explaining why the previous person’s statement is flawed. The only time that’s a valid opener is when the previous statement was clearly a yes or no question, otherwise it’s blatantly rude and abrasive. And extremely common on here.
