Wolvie, if I'm understanding you (and please correct me if I'm not!), you appear to be saying that because the surfactant helps the glysophate "stick" to the surfaces on which it's sprayed, the surfractant makes it easier to apply toxic levels of glysophate. But the study I quoted didn't say that; it said that the surfactant itself was believed to be toxic. This seems to me importantly different. That study, by the way, is at this site, and is available as a PDF.
