It seems inconsistent that openly gay and lesbian people are allowed to be members of the Lutheran Church yet children who are just suspected of being gay are not allowed to attend a Lutheran School.
Maybe that school didn't get the official statement from the church from back in 1996:
The Evangelical Lutheran Church in America officially and unequivocally welcomes gays and lesbians and their families. In an open letter in 1996, the Lutheran bishops reaffirmed this message and condemned homophobia and anti-gay discrimination:
To gay and lesbian members, we write to you in hope and out of faith. We all live with the pain of a church that experiences sharp disagreements on some issues. Yet we walk beside you and we value your gifts and commitment to the Church.
We repudiate all words and acts of hatred toward gay and lesbian persons in our congregations and in our communities, and extend a caring welcome for gay and lesbian persons and their families. We call upon all our pastors, as they exercise pastoral care, to be sensitive to the gifts and needs of gay and lesbian members.
