Tom Regan was nothing if not an honest man and so, rather than offering some sound bite or dodging the question, he said that this is a difficult issue. Animal advocates who often seem to believe that they require to have a snappy answer to every conceivable question can learn from Tom Regan because here he "admits" that advocates may not know the answer to everything, as though we have a well developed blueprint of the future to simply lay out before an audience.
However, Regan then asserts that there are some things that rights-based animal advocates do know for sure and that is that systematic use of other animals are rights violations.
