No one is being aggressive, except you being pointed out for lack of understanding on something in a sarcastic way (a joke in normal human terms), which you want to refer to aggressiveness to feel secure. The same reason you keep referring to your other post, because you can't take criticism be sarcastic or not, and want to prove to yourself more than others that you were "not lacking".
Inability to be criticized or pointed out for being wrong even remotely is a sign of a weak immature personality.
Might want to look that up, before trying to project your unhealthy state on to others.
If you were so stable, you wouldn't be having your issues with a sarcastic response. Only immature folk want to receive only praises in response to whatever they post because the "dopamine", and hide their shit behind, "oh you can be civilized", "oh you are not being sweat enough to not hurt my little whiny ego".
Do let me know if you actually sat down and cried over my sarcastic response and I will send some tissues over as a recompense?
