This is what I understand: Estrogen allegedly causes the "emasculization" of males usually starting with soy baby formula: lost libedo, low sperm count, breast development-- not sure about sterility. It is what men involved with sex change operations take to start growing breasts. Estrogen may cause early sexual development in females, as well as possible birth defects in fetuses of pregnant females. This info probably brought to you by animal testing. In nature, monster frogs as well have been linked to estrogens released by decomposing plastics. It allegedly can cause breast cancer or tumor development-- in fact since Doctors now discourage estrogen hormone replacement therapy for menopausal women, millions of women stopped taking HRT in 2003 rates of breast cancer have dropped dramatically 7%). That last bit was really the last nail in the coffin. Drug companies are pissed, of course, especially if they produced the pills. Their counter argument is that the women will eventually get cancer anyway. the baseline returns to normal within 5 years? -- so 2 years from now the doctors will be able to make another assessment.
I really dont consider it to be anti-soy propoganda. This stuff has been recorded for over a decade. I remember the 3 legged frog stories from 10 years ago, as well as girls reaching puberty at an earlier age. Soy is used as a filler in Omni food as well as cattle feed. I forget whether estrogen/soy is responsible for all the twins and multiple births or, if more female babies are born than males seeing that the "default" is female.
I believe I read somewhere that fermented soy products like Tempeh are not as bad as tofu. I think it is okay to eat some tofu and soy milk, but not to base your diet on it. I have cut my tofu soy use down by eating more beans and so on. I think that vegetarians become too dependent on soy and meat analogues. I never liked it anyway, so it is no hardship.
Oh, and I think acne is not caused by soy, or milk. It is caused by hormones. Testosterine, not estrogen, which both genders have in differing degrees, is responsible for acne. That is how they are able to stop acne by giving low dosage birth control pills (estrogen again). Dirt in pores and the degree you get the acne is up to your genetics. If your parents had it bad, you will probably not be very happy, and it is really not their fault either. The best defense is to keep clean to avoid infection.
