My point was that the phytoestrogens in soy are strong enough to affect your horomones, strong enough to have an effect on menopausal symptoms. Since most of the population isn't in menopause and half the population is male, this does not seem like a good food to eat if it's got that much ability to affect your hormones.

From what I understand the reason why soy phytoestrogens work to relieve those symptoms is because they bind to the receptors that real estrogen normally binds to. You're trading one that's natural for one that isn't... and isn't identical either, and is according to some studies is genuinely harmful.
On the other hand using progesterone cream made from wild yam, which is bio-identical to the progesterone you body already produces, has been shown to relieve the same symptoms by restoring a balance of progesterone to the natural estrogen in the body.
But then my research into these issues is still pretty new...
But, I WOULD NOT take soy, and I have avoided it for as long as it's been pimped as some sort of "perfect food" and has shown up in every processed product under the sun.
The exception to this is traditional fermented soy products such as miso and tamari that I use sparingly.
Our body is our subconscious mind, and anybody who thinks that their conscious mind is running the show is seriously mistaken. In fact the conscious mind just may be the most narcissistic entity in the universe, it thinks it's running the show. It's not.

Definitely this ^.
Progesterone is a wonderful thing if you're a peri-menopausal woman. I used Balance Creme For Women: Kokoro, LLC before I got my Mirena and it was pretty damn amazing.

Yes, studies on the net effect of these phytoestrogens give ambiguous results. They indicate that soy phytoestrogens can have an eostrogenic effect on some tissues and an oestrogen-regulating effect on others within one individual, due to differences in structure of various eostrogen receptors and concentrations of various regulators of receptor function. Then there's huge variation between individuals.
Taking progesterone cream is a much simpler, reliable solution IMO.
