I don’t recall ever seeing pro-GMO trolling, but I’m probably not haunting the kind of forums liable to get that kind of trolling. As others noted above, the Soylent discourse pages are largely GMO-neutral, so we don’t see much of that here.
I do see pro-GMO statements often made after anti-GMO trolling… we’ve seen a bit of anti-GMO trolling on these forums. And, to be honest, this thread feels more like anti-glyphosate trolling and anti-GMO trolling than a question about levels detectable in Soylent (if any.)
If it were about the question, the question could simply be asked. Instead, the OP opined about the need for everyone to learn “what the molecule of glyphosate is, what it does and how dangerous it is…” What’s more, the inclusion of a blatantly propagandic video on the “dangers of glyphosate and engineered food” turns what was otherwise a question into an anti-glyphosate and anti-GMO troll. Let’s be honest - Soylent is engineered food, and the opening post refers to “the dangers of engineered food.”
Also, just for the record, glyphosate is very rarely sprayed on grains just prior to harvesting. That complaint refers to the use of glyphosate as a drying agent, which is not prevalent, but more importantly would be useless just prior to harvesting. It needs to be applied weeks before harvesting for the drying effects to make a difference. In tests, application of glyphosate 5-7 days prior to harvest makes absolutely no difference in grain dryness or yield. But in tests where it was applied several weeks earlier, it ensured that more grains ripen fully and completely by the same date - ripening isn’t hastened for grains that were already ripening, but grains that were behind (late and high in moisture) would speed up and be ripe and dry in time for harvest. Spraying glyphosate just before harvest would allow time for any benefit, and would be a waste of time and money.
