That was quite a statement
(On a side note- there is a very funny section in Jonathan Gotschall's book, The Professor in the Cage, where he writes about the reasons why fighters with orthodox stances- i.e. the vast majority of boxers- absolutely hate fighting lefties. As the head coach at the MMA gym where Mr. Gotschall trains says, "all southpaws should be drowned at birth". And judging by the way Ronda Rousey absolutely got her (oversized) arse handed to her, I think he may have a point. Hell, I hate fighting against lefties, and I'm not even very good.)
It is important to bring in some perspective to understand how and where she went wrong. I spar, using hands and legs, roughly three times a week, and I can tell you from (rather painful) personal experience that when you're up against someone with superior boxing skills, reach, and footwork, and you simply insist on walking into everything that he (or in this case, she) throws, then you've only got yourself to blame. And indeed, that is precisely what took place.
