Blue Jay,
I plead guilty of over-exaggeration to make the point that Glyphosate is a very safe herbicide for humans to use, handle, and even mishandle (as most people do). You have to make a conscious effort of stupidity to seriously poison yourself with the stuff, and even then you have to try harder than you would have to with a lot of old-style herbicides.
But obviously the common sense quotient has fallen enough that people cannot see an overexaggeration without having smiley faces next to it.
For the record: Do NOT drink glyphosate or any other herbicide. While drinking glyphosate won't kill you (barring an allergic or sensitivity attack), it'll render your short term future decidedly uncomfortable, and you will become intimately familiar with your bathroom.
Good enough?
As far as whether I do not approve of any death-dealing product, there are many that I don't approve of. I don't approve of nuclear, chemical or biological weapons. I'm not a big fan of landmines or booby traps. I think riding a motorcycle without a helmet, while not criminal, is insensitive to the EMT's who are going to have to scoop up the remains of your brains with a grain scoop shovel if you get into an accident. Heroin, Crystal Meth, Crack, powder cocaine, ecstacy and other "recreational pharmaceuticals" result in misery everywhere they are used and made. I am less harsh in my opinion on marijuana, but seing as it's illegal, people should not use it...eventually it will be legalized (another ten years probably.) At that point I'll re-assess. I think smoking cigarettes is stupid, but if you feel you must, go ahead, just don't sign onto any lawsuits later. Anyone in the past forty years who claims they didn't know cigarette smoking was hazardous to their health is either a complete moron or is lying like an old rug. I used to smoke and I knew I was risking it all. Nevertheless I do not support banning cigarettes.
There are a lot of "death-dealing" products that are necessary for public health. Antibiotics, antiseptics, some pesticides (about the only thing that keeps malaria and yellow fever from becoming endemic up along the East coast as far as New York are pesticides that keep the populations down. ) Pesticide use is the only thing that keeps schools and hospitals from being over-run by cockroaches, rats, mice and other vermin. Places where pesticide use in those public places have been banned experience immediate expansions of those pests because it is not possible to maintain the clean-clean environments needed to keep them away when children and sick people are involved.
Likewise herbicides are used to keep invasive species like poison ivy,oak, hogweed, kudzu, Japanese Bamboo, Purple Loosetrife, Fragmites, etc. checked. They are used selectively along powerline rights of way to prevent trees from growing up into the wires and creating fire hazards or wind hazards. They are used along fuel pipelines at storage stations and at electrical substations to keep plants from threatening those installations. Transformer stations need to be kept essentially plant free to remove the fire hazards they would otherwise represent. handwork cannot accomplish this. Some chemicals are used merely to retard plant growth, lowering the mowing frequency from monthly to bi-or tri-monthly where high grass growth would create a safety issue by obstructing sightlines (along highways).
Pesticides and herbicides can be used responsibly or irresponsibly. This is true of most "death-dealing" products, in fact, this is true of absolutely all things. You can destroy a human being as surely by abusing their emotions as you can by shooting them. A person is just as dead when beaten with a hammer as when stabbed with a kitchen knife.
The crime is in the person who commits it, not in the object used.
