Well this has been reduced down to an argument about what constitutes athleticism. You seem to have a very narrow definition.
In order to be a competitive golfer you need outstanding hand eye coordination, balance, flexibility and quickness in order to generate the required club head speed and keep the club face square to the ball.
I think most people would think that all of those attributes constitute part of athleticism. And anyone who doesn't consider golf a sport is in the very small minority, I think.
You hardly expect people on here to agree with something you have a view on wes do you?
