There are a lot of noob mma fans for sure because it is becoming mainstream - more mainstream than boxing. However if you talk to knowledgeable mma fans there is a lot more to know (and to appreciate) in mma. For example, there are a lot of fans out there that do appreciate the technical wizardry of Machida's karate background although the uneducated fan just sees it as boring and running away.
There may be more injuries in mma, but the injuries that occur in mma tend to be far less serious and life-altering than boxing. MMA fighters can heal from a broken arm, broken jaw, cuts, etc. But boxers, who have to stand in there and have their brains bashed around for 10 to 15 rounds get punch drunk and ultimately are at risk of suffering long term brain injuries. This is far less likely to happen in mma because a fight is more likely to be stopped before the fighter takes so many shots to the head.
You find these types in every sport. Go to a hockey or football game and you get all these idiots. However boxing is a sport known to be infiltrated by the mob/mafia and organized crime and has been proven far too often to influence the outcomes in these fights.
Furthermore, I'd argue that organizations like the UFC (for all its faults) tend to protect its members in a far more humane manner than boxing orgs do. Just look at Mike Tyson as one example.
However, next time please do put that broad into a gogoplata. I hate that shit too!!!
