"The Godfather of Poker" Doyle Brunson says he no longer views Bruce Jenner as a hero ... all because of Jenner's decision to become a woman.
Brunson tweeted, "I can't believe Bruce Jenner is trying to become a woman? He was a hero of mine since I was involved in track long ago. #Sayitsnottrue"
Doyle continued, "this man was an Olympic champion that set all kind of records. That's a woman? My hero? Come on!" ... and his tweets triggered outrage in some.
The 81-year-old -- who's won the World Series of Poker twice -- eventually responded to the onslaught with a jab, writing, "He may still be some people's hero, but not me."
Brunson was inducted into the Poker Hall of Fame, he's won 10 WSOP bracelets in his career and is considered to be one of the most influential poker players of all time.
