I feel very uncomfortable judging people by the standards of the present, and I too wonder what the taboos of the future will be.
I must say, though, as an aside, that I remember 1998 as if it were yesterday, and I think that letter would have been taken as outrageous by most of the people I knew then. Granted, he was writing in Utah, which is and was a particularly traditionally conservative state.
Still… the letter would have had a certain shock value even 20 years ago, and I’m thinking the author must have understand that.
