Ethan having a pleasant conversation with Crowder about their children before pulling his stunt says all you need to know about Ethan, really.
Crowder didn't have a meltdown; he was simply a man who was pissed. His yelling was more than justified, especially with Seder and Ethan trying to yell over him first and not at all letting up on it. I can relate-- I have a temper myself, and I don't like it when I'm disrespected either. And hell, I find it hilarious that Crowder predicted that this would happen, too. You know the old saying, "If you want to piss off a conservative, tell them a lie. If you want to piss off a liberal, tell them the truth"? This entire thing is the embodiment of this stereotype, and it's pretty damn funny.
Ethan's actions are the actions of a shit talking child telling someone to meet them behind the school at 3PM for a fight, and then bringing his older brother to fight for him. Anyone who applauds his actions are spineless children, too. Of course Ethan's fans think it's OK to bring someone else in to fight for them. Dignity? What is that even? lol.
Again, I fail to see how Crowder "lost" this. And again, I fail to see how or why Crowder should have entertained these two jackasses after they so obviously disrespected him. They didn't deserve his time the second Seder started throwing the insults-- it showcases that Seder was never at all on board with a cordial discussion or debate with Crowder in the first place either.
