Narcissists tend to sound the same, because it's all lies about themselves and over inflating their own achievements because they can never get enough, have enough, do enough, etc.

Hogan and trump both would have had legitimate things to be proud of/brag about during their hayday; but because they are the way they are, it was never enough. It always has to be about them, and they have to be the best at everything. Their ego is fragile and any challenge to anything they do is met with extreme aggression to try and hide the fact that most of their accomplishments are made up lies.

Once you start down that path, you can't walk it back without admitting to every one of the lies you've ever told. And they physically can't do that. Like, their brain will not let them. You've seen trump try and acknowledge that he was lying by a judge and the best he can do is admit that the thing he's saying ISN'T true, but he believes it SHOULD be true, so therefore why shouldn't he be allowed to say what he personally believes is true, even if nobody else is willing to believe him? He knows that by saying it enough times, people will accept his lies as truth, there's no reason for him to stop.

Hogan's the same way. All Narcissists are the same way. It's their cornerstone behavior.
