That's a gross stereotype and just not true.
Our 2,500 lb. registered Angus bull is not aggressive at all.
Now, bulls are big and they can hurt you because of their massive size but they are not "wild" animals who "come after ya'." You would have to provoke them in some way for them to do that. Otherwise they are just big cows.
I rarely got off the school bus and not have to run thru the field if the bull was out...just to get to the house.
They all weren’t like that, but they seem to have a switch. Who knows what sets them off.
