UFC strawweight Michelle Waterson -- aka the Karate Hottie -- doesn't like that fellow UFC fighter Pearl Gonzalez had to jump through hoops to get cleared to fight with breast implants ... and says all women with fake boobs should be allowed to fight.
The NY State Athletic Commission conducted a review into Gonzalez before UFC 210 once they learned she had implants -- but ultimately cleared her to fight.
Waterson -- who's fighting Rose Namajunas this weekend at UFC on FOX -- says breast implants are no big deal .
