My guess is that most people that think venison has a "gamey" taste have never eaten a deer that was properly taken care of.
I love to hunt and have killed over 160 deer, but I am not overly fond of venison. To me, it is a very bland meat mainly due to the lack of marbling. I raise cattle and have killed a few that I have fed out, and I will take a home raised beef steak over a venison steak any day.
