I am not saying that you should not engage in peaceful demonstrations at a circus or whatever; I am just saying that you ought to be distributing literature and educating people about why ALL animal use is unjustifiable. Using an event like a circus as a focal point for vegan education is not necessarily a bad idea. As a general matter, however, I see single-issue campaigns as problematic, whether they are regulatory (making practice X more "humane") or whether they purport to be "bans" or prohibitions. They convey the impression that some forms of exploitation are worse than others and confuses people ~ Gary Francione
