So we are in agreement - both fighters are invoking real world issues to raise awareness of their fight, playing into it to create a sense of animosity that isn't truly there. DDP did it in his interview about being the real African fighter in the UFC and Izzy does what usually does, exacerbating the issue with histrionics and hyperbole.
People love this stuff and eat it up by the spoonful. Even Suredawg is filled with posters who love the melodrama more than the fights themselves. They're like women who read gossip magazines.
Adesanya knows what he's doing. He either galvanizes his fanbase with his actions, style and demeanor or agitates those who hate him even more with the same. One way or another, you're tuning in if you're a fan, or you're paying to see him get knocked the fuck out. It's the Mayweather effect all over again.
