so there has to be penetration to be rape? hmm...don't know about that.
secondly, how is it any more excusable because it is an animal being abused?
you have no problem labeling it abuse, but yet you have issues with it being called rape? why is that?
what if someone performed psychological experiments on you in which the end result was you to engaging in sexual activities which were completely foreign and unnatural to you but yet had no real control over? would that not be rape?
