Here's some reading for you:

(Partial) Vindication of Soy (http://www.brinkzone.com/soy.html)

Something to put you off eating soy for a looong time (http://www.t-mag.com/nation_articles/302poison.jsp)

Here's (http://www.wannabebigforums.com/showpost.php?p=762315&postcount=26) a handy post courtesy of geoffgarcia's journal (http://www.wannabebigforums.com/showthread.php?t=30970&page=1&pp=25) with a chart of various protein sources ranked by various quality measures. You'll see that soy scores higher than beef (and if I'm not mistaken poultry scores about the same as beef). Closer examination reveals that in actual fact it only has a higher score for PDCAAS, although if I recall correctly this is the "best" measure of protein quality. The lower scores for the other methods are from tests on rats who, possessing fur, require a lot more of the sulphur containing amino acid methionine than us humans, which soy is rather low in. In Brink's article on soy he mentions that rats fed soy enriched with methionine achieved scores on a par with casein.
