All Cris Cyborg needed was an opening. Something to point at. Finally, she realized that she was being mocked all these years, and damn it, she was going to let the world know. That's why when Ronda Rousey blasted media for saying she was fat (who said that?), Cyborg basically explained that Ronda and Dana White have been mocking her body image for years.
This, after years of not being able to get into the UFC due to lack of featherweight division (which she's cleared out) and with only the brave wanting to fight her. Naturally, what Cyborg should be doing is not calling out people for bullying, she should be calling out Dana White, and asking to fight the former boxercise instructor.
