No offense --- I don't know you or anything about you --- but this comment is like the Triple Crown of dumb GMO arguments.
1. That's a dude who was asked by Canal+ to give an interview about Golden Rice, a product that has nothing to do with herbicides, and is at the end of the interview asked to drink a glass of herbicide.
2. That dude doesn't work for Monsanto, isn't a "Monsanto lobbyist", and has never taken a dollar from Monsanto.
3. I don't need to watch Canal+ stunt interviews to know how dangerous glyphosate is, because there's something called "the medical literature", which documents people having drunk a half liter of the stuff with no effect.
4. But drinking a half liter of glyphosate-based herbicide is an extremely bad plan, because glyphosate isn't the only thing in glyphosate herbicide. Lots of routinely-used fungicides are extremely toxic to humans and found commonly in households.
5. Even if drinking a half liter of random herbicide was completely safe, I'd be upset if you demanded I drink it, for the same reason I'd be upset if you asked me to drink a glass of grapeseed oil or of human urine.
6. All of this drastically misses the point of glyphosate, which is that it's a very simple, broad-spectrum herbicide that is better understood than the selective herbicides farmers use for non-GMO crops. Glyphosate targets a metabolic pathway present in plants and fungus that isn't present in animals. That's not true of selective (grass- or broadleaf- targeting) herbicides. "Conventional" weed control programs are known to be dangerous to humans, rather than the targets of FUD campaigns.
7. If you're "inclined to agree with IARC" about glyphosate, unlike a significant number of scientists, I have bad news for you about cooking food --- meat or vegetables --- which is also 2A-carcinogenic.
