It isn't with a rally. I say this having protested for the first time in my life in the No to Prop 8 demonstration on November 15. The gathering of like souls who share a common goal serves to bond and empower those who assemble. A rally is a necessary beginning to bring civil injustice into public awareness. Having gathered together and embraced their common goal, those fortified people anticipate the next step.
But the next step isn't another rally, although they continue to empower and channel energy. Rallies serve the people who already agree on what change they desire. The energy rallies produce must be focused into the strength required to shift the fight into a new phase: changing the hearts and minds of those who can be moved.
I think that most of the straight population has been complacent on the issue of gay rights primarily because they think they don't know someone who is gay, and they don't understand how the issue hurts a fellow human being. Catchphrases, shiny mass-produced signs and rhyming chants are not going to positively influence most of those who aren't already in agreement. Straight people need to know the stories behind those signs, songs, and slogans.
After and between the rallies, whether you attend or not, you have the critical moment of public awareness. How do you use it? By telling your story. Not necessarily to the world, although some will take that risk. But step up and tell your story to those who already know you. Tell them what it feels like to be left behind; how it feels to struggle for rights that straight people take for granted like breathing; and what it is to be made to feel less than fully human for being different. Put a face on this issue. Come out, come out, wherever you are. This war will be fought on many fronts, but it will be won in heart-to-heart encounters by people like you.
