Just Wondering

If religious and moral views are not an acceptable basis for making laws, then is there any way to outlaw dogfighting, bullfighting, or cockfighting?

There is no injury to another person. If the bull is properly paid for there is no theft of property. Other cultures enjoy the sports so it is not innately repugnant to mankind. Morally, i think inflicting intentional cruelty for sport is wrong. But why would those views be OK if written into law, but not my views on abortion or gay marriage?
