Roundup is not a "pesticide" --- it is a "herbicide". It is designed to kill unwanted plants, not bugs.
Pesticide is used to kill unwanted pests, including plants and insects. Herbicide is used to kill unwanted plants. Insecticide is used to kill unwanted insects.
What it was designed for often has a few unintended consequences like many products do, chemically, electrically, or mechanically.
Erroneous labeling only distracts from any further argument.
When the author clearly doesn't even know/understand the difference between "pesticide" and "herbicide", why trust/bother with anything further they have to say?
Monsanto may well be a disciple of Satan but a proven lack of basic insight on the issue doesn't help validate the opinion.

> Pesticides are substances that are meant to control pests.[1] This includes herbicide, insecticide, nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insect repellent, animal repellent, microbicide, fungicide, and lampricide.
Still, "herbicide" is a more specific and accurate description of Roundup.
