Trump doesn't like same-sex marriage because he is a traditionalist golfer.

Trump compares his opposition to the legalization of same-sex marriage to his reluctance to use a new kind of putter.

“It’s like in golf,” he said. “A lot of people — I don’t want this to sound trivial — but a lot of people are switching to these really long putters, very unattractive,” said Mr. Trump, a Republican. “It’s weird. You see these great players with these really long putters, because they can’t sink three-footers anymore. And, I hate it. I am a traditionalist. I have so many fabulous friends who happen to be gay, but I am a traditionalist.”
