*sigh* If you insist.
I have never, in my 9, almost 10 years of playing sports, usually 3 sports teams every year, and watching around 100-200 sports games, live, every year, seen anyone purposefully hurt, kicked, tripped, or anything.
About your friend getting kicked. He is playing soccer. I don't think I really need to explain this any further.
Has your sister ever been helped up after she has fallen down? How exactly did she learn? Did someone ever help her then, or did she learn by herself?
And what exactly is athletics? If it is like physical education, then that is not really a sport, and not really competitive. If it is not like PE, I don't know what it would be.
And lastly, do you watch professional sports at all? I do, and every day I see people in the games helping each other, and being friendly.
Baseball: A guy gets a single, and he starts talking and laughing with the player at first base.
Basketball: Someone falls down, and a player from the other team grabs his hand and pulls him up.
Football: A player gets tackled, and then the guy who tackled him helps him get up.
Tennis: Nadal beats Federer again. They go up to each other and shake hands and talk.
Golf: Two players go the 18 holes together. All day they talk about stuff, and give advice on what they would do for this drive, or the angle of the putt, etc...
I won't talk about this anymore, don't wanna turn another thread into a huge argument.
