Maybe, as is typical on campuses, you have one or two people running around doing most of the advocacy around LGBT issues. Maybe, you have a widespread coalition of straight supporters and LGBT people from all walks of life. All these forms of activism are highly effective. A problem faced by many of these actions, however, is that they are detached from students daily life. Homophobes can just avoid rallies.
Educational events end up preaching to the converted.
Now picture a slightly different event. Picture participants of all sexual orientations, going through their daily walks of life in an act of highly visible protest. Participants let their classmates, their teachers, their office mates, the cashier at 7-11, know that they support and advocate lesbian, gay, bisexual, and transgender rights. At the same time this visibility is fostered, the event allows for a period of inner reflection about the consequences of being invisible and silenced, bolstering an inner determination to speak up. Picture the close of the event featuring educational follow-ups and rallies, employing those events activists have found to be so effective.
