If an organization gives a group, a chance, then they will only inspire others from their group. You may not necessarily believe that the women who are fighting, fight with as much skill as men, but by the women having an outlet to be seen, there is a new generation of girls watching that will begin a mixed martial arts career from their youth into adulthood.
And these seven-year-old girls that are taking karate, watching UFC with their dads these days, may want to continue the MMA route and in 13 years, have a decade and a half or so of designated Karate/MMA training and be able to put on quite a skilled show.
Now I personally have been impressed with a number of female combatants in the sport as I have been with various male athletes. Neither sex has its lineup of flawless fighters, but both certainly have their own talented representatives...in my opinion.
Let’s say that UFC only allowed Caucasian males to fight. Throughout 20 years, all you saw were white dudes fighting each other. Then all of a sudden, you saw black guys, Hispanics, and Asians fighting. If you were not impressed right away and cut their opportunity short, then the aforementioned would never inspire youth from their respective races to learn the sport of MMA from a young age and carry that into adulthood, to then be fine representatives in a decade/beyond.
Instead, you allow males of all races to fight and hopefully each one has its own set of high-quality martial artists that inspire others to join the fight game. I would recommend take this approach when it comes to your perception of female fighters going forward. It’s a bigger picture kind of thing.
To each their own though. Just my opinion on the matter.
