Do you have any respect for other living things? To consider cruelty and torture something that should not be prevented by law is amazingly sick. I sincerely hope you do not own any pets. It sounds like you desire the 'right' to harm other things in any way you desire. That goes beyond libertarian and right into derranged. I fear for an animal's safety near you. And to think that you also believe that it's OK, or even proper, for children to witness such depravity!
Human life is sacrosanct. Animals have zero rights and any attempt to give them rights is based on emotion rather than logic. Why should you not be able to kill a dog, if you can kill the mouse chewing though food containers in your cupboard?
It is your types that want to equate animals with humans who's actions eventually leads to unspeakable acts committed upon people as the value of human life becomes meaningless. It is you who stand in the way of research to help people at the expense of "torturing" animals.
