Why does Trump get pissed every time someone contradicts his claims?

Its not every time , it just seems like that becasue of the pure volume of shit coming out of his mouth.
He only gets pissed when he's put on the spot over his bullshit , like on a tv interview or something .
then he responds to the question with "You're not very nice"

Most of the time he's sat at home pumping his lies into the "Truth" echo chamber he bought , where he can ignore if any criticism but theres minimal pushback from the devoted Truthers

He can't handle criticism in any form, nor the intellectual capacity to rhetorically debate when someone contradicts him.

He will just change subjects and say how Democrats and their woke agenda are ruining America with cancel culture , and ever other dogwhistle for the far-right . Nancy Pelosi, China whatever , it doesnt matter. The point is he can't debate. Why else is he not even participating in the Republican primary debates anymore?

He can't handle being in a situaion with someone asking him questions, or even share the stage with another person as an equal. That goes against everything he stands for about being a totalitarian. He can't even put himself in a position where he's not in total absolute control.

The same reason the liberal news covers for Joe.

He'll whine, whing, shout, yelp, yawp, scream, convulse, bellyache . . . even stage an insurrection . . if he doesn't get his way.

And being disagreed with -- being contradicted -- is just such an example.

In his mind dissent in any manner is a vile offense.

He is been calm, but dumbass contradictions deserves a smackdown.

Quite simply, he is a narcissist.

The same reason Joe Biden gets pissed at the Press and storms off when the Media begins calling him out on shit he doesn't like, that's why
