Be proactive, not reactive. Designate a day for all of the queers to wear blue jeans. Be sure to publicize this in the papers. Hold a candle light vigil for the damage done to the queer community through hate crimes, compulsory heterosexuality, etc. Line a well-used sidewalk with rainbow flags.
Many libraries order books based on the interest in the topic.
Encourage your queer group to join local parades and celebrations. Practice queer acts of kindness and senseless beauty. Donate posters of queers in history to your school's history department or English Department, etc. Or go through and place pink triangles next to or on the posters which depict authors who's sexuality are often hidden such as James Baldwin, Walt Whitman, Virginia Woolf, etc. Make use of large banners and hang in visible places.
