I have no feelings about it one way or the other. To me it's the same as thanking your trainers, family, friends, sponsors, or favorite flavor of ice cream. I really don't get outrage one way or another. Bendo gets a lot of hate for it but I don't see why. Thanking God is just a personal expression of belief.
Using the post fight interview to preach is an entirely different animal though...
PS Am I the only person who - just once - wants to see a fighter thank Satan for his victory? Bonus points if it's a Greg Jackson fighter.
That is not dead which can eternal lie and withs strange aeons even death may die.
