Honestly, I don't feel much like you were being as good as you try to portray yourself as. Reason being, you blacked out the very top part of that chat - what else did you block out?

"You should reread your skills."

There is no way except negatively for someone to take that. None. You literally threw them under a bus in the first line of the conversation that we can see. How do we know there wasn't more beyond that?

What more, why did you feel the need to black that out? Surely you realise your own words are just as toxic as they were taken

So, while I won't disagree that people are WAY TOO DAMN DEFENSIVE... in your case? Completely justified. Treat people like crap and they shut down. Treat 'em with respect and they'll open up to you.
