Pointing out that the UFC is favoring fighters from that market on a "UFC Mexico" card in which their goal is to create stars and champions in the Mexican market is not racism, don't bait like that. There was clear preferrential treatment to judge the fight in a way that kept the belt on Grasso, that's not even debatable, say what you will but round 5 was not a 10-8 for anybody under any sane scoring criteria, that's a blatant fix called in by Dana/UFC after realizing it would be a Valentina win.
That's corruption, plain as day, it doesn't matter who you thought won or anything, you cannot be sane and agree that round 5 was a 10-8 for Grasso, the fact that a professional judge saw it that way says he was paid to see it that way, to make the fight a draw, keep the belt in Mexico and create a trilogy fight they can use as another headlining title fight later on. This is business, not sport, expect more bullshit like this as the WWE effect takes hold of the UFC, Vince MacMahon calls the shots now so expect all sorts of Montreal Screwjob-level fixing of matches.
