Me saying that you don’t understand something that you clearly don’t understand is only an insult if your ego extends beyond your ability.

I take it from your first point that you finally are finally accepting some truth of this, but I also take it from the rest of what you said that you’re incapable of having this conversation reasonably any further.

Have a nice day.

A bunch of advice when socializing with people:

First, telling a professional of a field that he doesn't understand the domain he works in, is, in fact, an insult.

Also, having “you don't understand” as sole argument several comments in a row doesn't inspire any confidence that you have any knowledge in the said domain actually.

Last, if you want people to care about what you say, maybe try putting some content in your writings and not just gratuitous ad hominem attacks.

Lacking such basic social skills makes you look like an asshole.

Not looking forward to hearing from you ever again.
