We know from history that lesbian, gay, bisexual, and transgender people have always existed in society (Campos, 2003; Sullivan, 2003). Lesbian, gay, bisexual, transgender, intersexed, and queer/questioning (LGBTIQ) individuals, collectively known as sexual minorities, represent approximately 10% of the population. As many as nine students in every classroom of 30 are in some measure affected by sexual minority issues (e.g., having a gay or lesbian relative or being gay oneself) (AFSC Gay/Lesbian Youth Program, 1991). “Yet even with this substantial number, the code of silence in our nation’s school systems concerning homosexuality remains” (Fontaine, 1997, pp. 101-102).
