Yes, I agree that there are too many pesticides in fruits and vegetables nowadays. Whereas in the past crop growers would use water-based pesticides that required frequent re-application, now there is a trend of using residue pesticides that do not come off with rain and sun-bleaching. This results in fewer sprayings, less labor expenditure and more product yield. With most fruits and vegetables, there is a protective skin or covering that hopefully prevents at least some of the pesticide from seeping or absorbing into the flesh of the fruit or veggie. So a thorough washing of one of these items may not remove all of the pesticide, but removing the skin of the food may be even more of a way to avoid pesticide residue. Personally, I try and avoid any fruit or veggie that grows exlusive in the ground and does not have such a protective skin, unless I can be sure it is grown from a source that uses proper crop rotatation and few pesticides.
However, with soybeans, genetic engineering is done so that certain pesticides can be introduced into the bean itself. Since up to 60% of the soy in this country is harvested using genetic engineering, there is little reassurance that soy products are safe from these methods unless otherwise stated. So no matter how carefully it is washed or cleaned, we are eating pesticides in soy, most likely. The toxic levels of soy pesticides are beginning to come to light based on studies done on soy-based baby foods, which apparently show very high concentrations of pesticides such as dieldrin, which is very similar to DDT in it's organochlorine structure. Plus some recent research has shown that high levels of phytoestrogens such as what is found in soy has been compared to the effects of DES diethylstilbestrol, a toxin linked to many different diseases and conditions. Soy has also tested positive for the presence of foreign genetic material because of cross pollenation and contaminated seed stock. And I really think we're just beginning to scratch the surface with the problems with soy.
One problem specific to soy is that it is not easily digested since it is more of a waste product than a human nutrition source.This is shown in the history of soybeans. Digestion of soy products is limited by certain soy proteins called "trypsin inhibitors". These trypsin inhibitors prevent ready uptake of soy protein. This inhibitor also blocks the absorption of other proteins taken in at the same time. So perhaps the risk-benefit of soy protein over the high levels of pesticide genetically modified within in my view may not be a worth trade off. There is also recent evidence that soy may inhibit the tyrosine functions in the body and thereby prevent certain amino acid metabolism. Plus soy is high in phytic acid, which is known to inhibit uptake of zinc, iron and many other minerals as well.
Soy products in this country are a result primarily of enterprise driven goals of producing a cheap, edible food that is easily processed. So I'm not convinced that it was health the industry had in mind when it began using this as an agricultural product. As quoted by an excellent physician, "Money seems to drive many systems in directions which does not optimize people's health."
Again, I'm not absolutely convinced that soy is estrogenic in humans, however, more and more research is beginning to shed light on this controversy and perhaps in the future it will be more evident. For now, I wouldn't necessarily avoid soy for the estrogenic effects it MAY cause, but rather for the problems of pesticide content, difficulty with digestion, apparent inhibition with other necessary minerals and nutrients and genetic engineering problems specific to soybean.

Animal products are also steriod-pumped.
This may be a matter of semantics, but "steroids" are not given to animals in this country. rBGH's and other growth factors, yes...but steroids, no. At least, not legally.
