Since when do you have to respect a fighter to be a fan?
Lots of great fighters are pieces of shit outside the ring. Lots of fans don't know a single thing about their favorite fighters besides how they fight inside the ring.
Mayweather was a woman beating sack of shit and he sold more ppvs than anyone who ever lived. Pacman called gay people animals and tried to use his governmental power to outlaw condoms in the name of God while his wife was on birth control. Adrien Broner pistol whips and robs people who beat him at bowling. Tyson Fury thinks women who have sex outside marriage should be stoned(with rocks not weed). Mike Tyson robbed old ladies and did time for rape. The list goes on forever.
The big Canelo fans I know just like watching him fight. Respect plays no part in that at all. It's entertainment value and that's it.
I personally think Broner is a HUGE pile of shit and I am very much looking forward to seeing him fight on Saturday. Already have some big Costco ribeye steaks and a few beers in the fridge. Fuck respect, I just enjoy boxing. So do lots of other people.
If I wanted to spend Saturday watching people I respect I'd be sitting outside the fire station staring at firefighters which is probably illegal and most certainly gay.
