People from east and southeast Asia have been cultivating and eating soy beans as a staple food since before Babylon. I mean that literally; there is evidence of soy bean cultivation in what is now China from like 7000 BC.

It’s tough to take a phrase like, “Soy makes men weak,” as anything other than racism when it puts down a quarter of the population of the planet. At best, it’s ignorance, but in my experience the people who hold this opinion don’t change their mind when you explain this to them.
