Now usually these kind of tirades come after a manager/coach gets tossed for arguing something like balls and strikes and the call could have gone either way.
Dude has every right to go bananas on the ump and his staff. He called him out when the ball was on the ground, that seems like Ump 101 stuff. He even watched the catcher pick it up and called him out again.
Then to make it worse, the whole crew came together and talked about it and STILL said he was out.
Coach gets a pass from me here.
