There is definitely a very thin line in the sand, if you will. I think of Sergio Garcia who is notorious for having a hot temper, and I think his behavior is unacceptable. However, the occasional outburst from a Hatton or Rors, I don’t mind. They are passionate about their sport and they expect better from themselves. Generally speaking, nobody really complains when a baseball, football, or basketball player gets upset and throws a temper tantrum. I feel sometimes golfers are held to such a different standard. On one hand people will say golf isn’t a sport and on another, when they have emotions like a normal human or elite athlete, they get mad that they are bringing negative energy to the sport.
So the long of the short of it is this, an occasional passionate outburst, in my opinion is totally acceptable, they are elite athletes that are also human and expect a lot from themselves. It’s ok to show that emotion, both positively and negatively.
