Actually, there is a higher probability of the writer being black than white. The nation of islam is very much against race mixing as is the new black panther party.
There is also a greater likelihood of the writer of the letter being a woman. Many black atheletes, actors, professionals view a white wife as a trophy or a sign of their personal success.
To disagree with those to points would be a denial of reality.

The reality is ...to quote from the article.."One of the letters "threatens bodily harm to Taye Diggs,"

If the letter writer was a black woman the obvious person to threaten would be Idina Menzel not Taye Diggs, and the KKK is also very much against race mixing. This could lead one to the conclusion that the letter writer was a white man.

The truth is you have no idea who the letter writer is. There is not enough information for anyone to know for sure. The fact that you would use your preconceptions to even hazard a guess says much more about you than it does about the letter writer.

I met a woman applying to medical school today who is black with a white husband.

Says it isn't really a big deal to her - but that in her church she has noticed she hasn't been welcomed by some.
