Well the point of the post is to nit pick a hypothetical since I doubt many people, much less vegans are actually eating those plants, we're all casing judgement here. Especially since not everyone definition of veganism is the same. To me if its dietary and chemical then obviously it doesn't matter, but if the 'product of animal suffering' is someones black and white philosophy then to me Flytraps seem about as vegan as consuming the flies they eat (which is only like one month). While an insignificant amount, it is measurable is all I'm saying, literally a technicality but that's why its a basically hypothetical post online I suppose. In reality, everyone draws their own line somewhere, from the jainists who breath through cheese cloths to protect any microorganisms they can to the carnivours.
