They shouldn't be banned either.
I road a stupid horse once or twice. Named Wildfire... Wildflower... or Retarded-horse.... whatever the case- the horse was a bastard... aparantley there are a lot of retarded horses.
I crossed the path of a few bull red faces... they looked as though they would charge and got mighty pissed when I approached their cows... Ban grazing?
When I was 3 we had a big Rhode Island rooster that roamed the farm... and it would attack anyone who crossed its path... there was something wrong with that bird... and since I seen many stories of nutty roosters that attack.
