Why? A few reasons
1. Because mass celebrities like Kobe and Lebron discovered her recently and were tweeting about her. This incited the hoards of morons that hero worship basketball players, hip-hop, pop and tabloid culture....those that occupy the lower-avg IQ range of 75-100.
2. Mayweather destroyed millions of person's hero in Pacman after whooping him in the highest grossing spectacle of all time. After this globally seen whooping, people were hungry for a new hero to dethrone, or atleast think they could dethrone, the antihero known as Money May. Conor was wise to this void and offered to fight May. However, the legions of morons, fueled by the likes of Clay Travis, think a fight with RR is not only possible, but that RR is a more dangerous threat to MM than CM. They also find poetic justice and an extra dose of emasculation claiming that a woman could beat MM, especially since the leftist media jumped on his nuts for domestic abuse.
3. As someone already mentioned, the false narrative has spun that Correia was claiming that Rousey had a genetic predisposition to suicide, since Rousey father killed himself, and she was suggesting that after she beat Rousey, Rousey would be genetically predisposed to taking her life. Rousey has a hard on for "people talking shit about her family" (See the Tate fight), when that never really has actually happened to the extent that it has been suggested. Millions of morons have what I call "movie brain" where they live thru others, have uberly dramatic grandeur and just wait for the day when someone talks horrible shit about their families/loved ones so that they can lay an epic honor beating on their ass. Dana was wise to the mentality of these idiots and in effort to hype the fight, suggested that Correia read Rousey's biography and was insulting a sacred code of conduct, fueling the fire, even though it is an unproven/false narrative but great for inciting the rage boners of morons.
Rousey is a safe bet to quench said boner of rage since she is 100% paired against cans of epic proportions (hence why they got mcmann in there quickly, before she had time to learn standup/develop her game). UFC is magic because they make the morons and uneducated folk believe that Rousey is fighting legit competition. Bethe was an artfully developed can, in the sense that she had a fluffed up undefeated record and was purposefully paired against the 4 horsewoman, even though she was mostly dominated by these local level talents that went 1-7 in UFC.
All in all, people will just read the headlines and jump on trendy topics and the UFC know this. The UFC know that as long as they say "Rousey is fighting legit fighters", the mentally lazy hoards of people will not actually look any deeper. UFC is a stronger monolopy than it ever has been and blacklists those that speak the truth, truth which is contradictory to their agenda....thus, no major media outlets are calling Rousey the untested, artificially created commodity that she is that is afraid to take on the only legitimate task that exists for her: fighting Cyborg.
We are essentially witnessing Kimbo Slice and Gina Carano embodied in one person here, and this whole phenomenon makes it no secret why when Kimbo and Gina were paired on the same card, it was the highest viewed card in history...both were untested, later exposed, but the greater population did not care and just wanted to be fooled and entertained for the night. Fantastical calls of "Kimbo could beat Fedor" drowned out more logical assessments until Petruzelli silenced the all w/ truth. UFC learned a valuable lesson from Seth Petruzelli and will not make the same mistake that Elite XC did: they will not let their cash cow lose and the Cyborg fight will NEVER EVER EVER happen.
