Wow . . . a lot of God hate on this board.
If a fighter wishes to thank God for the victory, that is his personal choice to do so. For the American's, it's their constitutional right to do so.
As far as being pissed about seeing it or saying this sh** has no place in this sport . . . I say get over it. You don't have to agree with a fighter's choice to thank God, but you should respect it. If they have a personal relationship with God and wish to thank him for the victory, let them. Who is it hurting? That is between them and God. It has nothing to do with the opponent (or in this case the viewer) or their religious preference. That is a personal relationship they wish to acknowledge during their moment of victory.
I have debated this with others before. I have never understood why so many non-christians get so upset when it comes to someone else thanking God. Does it hurt you physically? Does it hurt you mentally? Or is just the simple fact it annoys you? My guess is that it just annoys you. GET OVER IT! I personally can't stand it when fighters start thanking their coaches and sponsors after a fight instead of answering the actual question they were asked. But, if they have to throw their coaches and sponsor's names out there . . . meh . . . I'll just mute the TV or just ignore it.
The bottom line is this. If a fighter puts his heart and sole into training, then leaves everything he has in the cage to entertain us . . . the fans . . . I say let them thank who they want. If they want to thank their 98 year old grandmother who has one leg in the nursing home, I say who cares!?!?!?!?! If it pissed you off, get over it! I'm sorry it annoys you but criticizing one's personal choice to thank who they want is just retarded.
