What's the problem with vegans consuming soy long term? Your second link talks about soy fairly positively and your first link only mentions soy once in the context of a lot of other foods (and really it's rare for a food to be purely good, e.g. lots of plants contain toxins). Based on those links I'd probably conclude soy consumption is very far down my list of foods to be concerned about.
There's even this quote: "Studies on vegetarians who eat diets high in plant foods containing anti-nutrients do not generally show deficiencies in iron and zinc, so the body may be adapting to the presence of anti-nutrients by increasing the absorption of these minerals in the gut." indicating that it may not be a real problem to eat foods that contain these 'anti-nutrients'.

Vegans I have known said that a heavy soy diet over an extended amount of time does impact the thyroid more. While it was anecdotal hearing this, it was not anti-soy, just, about soy quantities over a long time, and the need for a diverse diet for vegans too.
Some of the anti-nutrients seem positive in one way too, which makes it even more complex.
