There's a reason the UFC and WWE are so popular, they are entertainment where the more flamboyant and outrageous you are, the bigger the contract ($$$) you get. I don't think he is a saint but he also understands the game and tries to maximize it to his benefit, and I can't blame him .
I also like to see him beat the crap out of internet trolls until they cry... Like this guy who was known for going to gyms and would just start fighting guys to try and prove how strong he was. His mouth went a little too far when he started in on Wilder.

There is a lot more to the back story documented on the internet too, like when the troll decided to bring his daughter, the one mentioned above with spinabifida, into the conversation. I'm surprised Wilder didn't kill him.
