Well, since glyphosate itself isn't a GMO nor is it produced by GMO plants, I'm not sure what your point is in regards to GMO food since glyphosate has been in use much longer than transgenic technology has been around. BT toxin on the other hand, is a GMO byproduct/pesticide that is perfectly safe for humans in all tested quantities, and demonstrably so.
You're going to have to produce citations for every one of those claims also: that anyone ever said glyphosate is completely safe (nothing is, dose = poison), that "they" said it wouldn't be detectable, that it's been detected in "pretty much every person alive", etc. It's detectable in blood and urine of farmers because they're exposed to it at much higher levels than the general population are, through both inhalation and skin absorption, not through digestion. When you consider how little is actually sprayed onto a field, compounded with harvesting, storing, transporting, processing, and finally cooking food, that there would be any detectable residue of glyphosate going into your mouth, bypassing being digested by your digestive system and entering your bloodstream, that's a highly, highly dubious claim that you're going to have to show some serious evidence for. Where are you getting these claims?
