I think you've summed it up perfectly. I luv watching the UFC, Pro Boxing & Pro Rassling (Yes, I know it's fake) because I luv the brutality of it. I luv the bloodsport factor of it. I give those Pro Fighters/Boxers/Rasslers a hell of alot of credit for stepping into the ring because they know they could receive the beating of their life. But they're trained professionals who know what they're doing & the sporting authorities wouldn't let them step into the ring if they felt the Pro fighters/boxers/rasslers weren't ready for it.
Olympic fighting sports have no brutality & no bloodsport... so therefore, they don't interest me even one iota.
