supports Singer's consultant background on Pg #2 of the document (his attached bio.)  I used this reference as you have already unfairly attacked two previous sources of the same information as "unreliable".  Since this particular source was *already* being used by the article in support of a different claim  and since you've left this source in across repeated edits  you obviously cannot attack it on the same grounds.   In short, it was used to short-circuit your POV-pushing attempts.
