People that read that are wrong (at least sometimes), since Linkedin shows degrees-in-progress and completed degrees the same way. Not ideal interface, for sure, but that's what it is. People that do not know that make mistakes. It's their mistake.
> Could that be an accident? Might it just be incompetence? Maybe.
Surely, it may be incompetence - not understanding how Linkedin profile works. But it's not Damore's incompetence.
> That he then quickly removed things when called out with neither explanation nor apology
If people misunderstood what was on his Linkedin page, and undeservedly called him a liar and attacked him for that, and he removed the controversial item despite it being true - I think demanding apology from him for you misunderstanding him and falsely calling him a liar is taking the entitlement thing too far. If somebody owes an apology, it's people who called him a liar despite him publishing completely true information - but of course I do not hold by breath for that.
> fits in with the "lies to make himself look good" narrative.
Surely it fits your narrative. The problem is it is not true.
> A person who had made an innocent error generally feels bad about the error and says so.
Nobody owes you feeling bad for telling the truth and you misunderstanding him. It would be nice if people who did the misunderstanding felt bad and did not blame others for their mistake, but I recognize this is not how the Internet works. If you misunderstood something, it's other guy who should be feeling bad for not working harder to prevent any chance of you making a mistake. The other guy is always responsible, he's clearly either a liar or an idiot for letting you to misunderstand him.
> Your thing about LinkedIn form design seems to be pure fiction. I just checked: you can enter any text you like, including no text at all.
That misunderstanding thing happened to you again. I haven't said you cannot enter free text in Linkedin. I said the form does not have completion status for education. Yes, you can hack around that by adding various text to a degree program name or any other field. If Damore knew in advance there would be a mob of hostile attackers scrutinizing everything he ever did under a microscope to find even a tiniest flaw and blow it up out of proportion, he would probably do it too. But he just wrote true facts about his educational record, without thinking about being extra defensive and using tools given to him by Linkedin. Linkedin provides tools to set beginning and end time for educational record, and program name, but does not have a setting for "incomplete" or "in progress" status.
> This is not a personal attack; this is me pointing out facts of his behavior and reasonable inferences.
You "reasonable inferences" - which, as far as blaming others for your misunderstanding goes are not reasonable at all - are what is the personal attack, since they seek to impugn Damore's character without addressing his actual arguments. That's the definition of personal attack.
