>>42400891To add on this, his "I can do no wrong" attitude is what further cements it. Many people have pointed out errors in his site but not to mock him, on the contrary, simply to give a hand and make the site better, but all they get in return is Joe being insanely hostile and defensive. It's like when you hold the door open for someone and they go "Um wow are you calling me weak? I can hold the door myself, asshole" when all you were doing was trying to help.
He could easily be like "Hey thanks! I didn't catch, thanks for telling me!" or something like that, maybe even a neutral response like "Noted, much appreciated" but no, he's incredibly hostile because you "dared" hurt his ego.
