I wend under attack from the Animal Rights bunch after the hoopla over the Doc killing Clarence the Cross Eyed lion (look him up ) a few years ago. Hacked form GB and NZ, Canada in addition to the US. Vile, nasty lot that can give you a head ache in a hurry. Fortunately, there are ways to punish them.
