I don't know why you'd be pissed at Dana for what he did. In the real world there are consequences for your actions. What Jesse did wasn't cool at all. It's pretty clear from the rest of the show that Jesse may have a bit of a drinking problem. Some people need a wake up call to realize they may have a problem. Hopefully Jesse will learn from this and make some changes.
You may hate him, but Dana has done a lot of work to change the stigma that MMA is a bunch of thugs beating each outher up. Dana kicked 2 guys off the show for fighting in the house. Think about that, 2 guys got kicked off the show for fighting on a show about fighting. Did you think Dana wouldn't kick a guy off the show for acting like a jack ass out in public?
