A few years ago a fishing buddy of mine and I had a mutual friend that was anti-fishing. He wasn't a crazy PETA person, but he did think it was a little crule. We started to ask him if he wanted to go fishing with us and eventuly he would tag along. He wouldn't fish, just hang out while we did. I started bringing an extra rod with me and after many session of him sitting on the bank being bored he started to fish. Much to his suprise, he stared to enjoy it. Less than a year later he bought his own rod and reel!
Score one for me for converting an anti-fisherman!! ;D
