I get what you are saying, dehumanizing anyone is wrong.. But I understand Ronda's concern. Cyborg was caught cheating, not only cheating but cheating in a way that puts other fighters health and safety at risk.
It just seems a lot of people are taking these comments by Rousey as something horrific but we have seen much, much worse from many other fighters who had no facts to back up their claims.
Ronda's concern is just getting destroyed. Just like it was when she earned her title shot at Cyborg in Strikeforce (before she tested positive) and instead dropped to 135 to take the easier fight.
