I think a lot of the early backlash against soy was more targeted at soy milk in particular. Soy milk was one of the first widely marketed ersatz milks, at a time when virtually all “milk” in the store was actual cow milk and Lewis Black had a hilarious comedy bit about how there were already too many kinds of milk[1]. There was also an infamous 2008 case study of a man who developed gynecomastia while consuming three quarts of soy milk a day[2].
