What are “bloodless” or Portuguese bullfights, and are they legal in the U.S.?

So-called “bloodless” bullfights, legal in many U.S. states, involve teasing and attacking the bull. Although tormenting and abusing the animal is part of the show, killing must be done outside the arena. But just like regular bullfights, bloodless bullfights send the message that animals are nothing more than objects for us to abuse at will.
