Why are people against bull ridin?

Im 14 abd ride bulls, i know from personel experience that the bulls are not abused in any way. If you ever see two bulls fight each other out in the pasture then you know that there is NO way that humans can possibly deal punishment to bulls the way they do to each other. It is a proven fact that rodeo bulls live longer and probably happier than most regular farm bulls. NEVER do we kill bulls after rodeos, thats bull fighting in spain which i am 100% against. We do not dig our spurs into the bull and the spurs we wear are dulled and just for show. The flank strap is not tied around the bulls balls just behind them, it does not hurt the bull in any way, shape, or form. And the bulls who buck in rodeo's LOVE bucking, if they appear to not enjoy it then we dont use them for rodeo's anymore. you should see a young bull prance around the arena after he bucked of a young cowboy and if you look in his eyes you can tel he is extremely proud and happy. so why the heck do yall think this is animal abuse!?
