It's fine if you've never watched boxing or know nothing about it, you don't have to comment and be an expert.
Saying people watch boxing to see people beat the shit out of each other is false. That is the underlying reality of boxing but not what makes it popular. It's like saying NFL fans watch the NFL for bone crunching hits. Yes, that is the underlying constant threat in the sport, but most people (today) don't watch it to glorify the big hits, they watch it for the competitive games, strategy, and athleticism.
For me, I like boxing over MMA because I don't like how violent mma is. I'm sure if I watched MMA more I'd get an appreciation for it, but as a casual observer I hate it, makes me uncomfortable to watch a guy get pinned on the ground and then get his head bashed in with elbows till he passes out.
