As reported by Salon:

After the Boy Scouts of America sent Rep. Barney Frank (D-Mass.) a letter saying it would be “honored” if he would lend the organization his support, Frank sent the following note in reply: “I was surprised that you wish my support. Where there is much about the Boy Scouts that I admire and I am a former Scout myself, I was under the impression that you considered people like myself to be unworthy. I am a gay man, which, according to your policy, means I am neither ‘morally straight’ nor ‘clean.’ It seems hypocritical to ask me to sign it.”
