The crowd is full of shit. MUSCLES LOVE ALL GENDERS! Both men and women have muscles, therefore men and women are equals!
Trying to kill Yuri aside, which was totally predictable, I'm glad Barbandogas realized that that unleashing full MUSCLE is a sign of respect.
Also, the fact that the dragons were somehow flexing along with Yuri was awesome. Muscle resonates with muscle, water with water. Two of a kind.
I don't think Muscles are god though. Muscles are a force of nature that flex, no more, no less.
