Scientific literature contains more articles on fruit flies than on human sexuality. Many researchers want to leave it alone or leave it to the church. Think of the difference that removing homosexuality from the DSM made in the social acceptability of being gay or lesbian, not to mention no longer a psychological illness. Once science endorses all sexual identities, social mores can change, stigmatization can be made to become extinct, and maybe just maybe we can get to a place in society where once again sexual identity as a construct does not have to exist. But until the negative connotations are replaced with respect and regard, a complete society cannot be realized.
Science has the ability to be the catalyst for change.
Science can be a change agent for altering homonegative attitudes, spurring social change, and increasing civil liberties for all of those who experience oppression because of their sexual identity.
