Glyphosate IS toxic. If it was fertilizer, weeds would grow, not die. It's a sort of no-brainer. On the other hand, the real question is, "does it contribute to harm in humans, animals, sea creatures, insects, and the plants we want to survive?" The actual answer seems to be "Yes," since there is more and more research demonstrating it is toxic.
We all need to be more careful about poisons, whether we use them intentionally or not.
This is the beginning of enlightenment about all these things, and as we all begin to understand it, there will be lots of conflict, with people who have interests on one side or the other doing all kinds of things to assert or resist the position that poisons are well, "poisonous." Same thing happened with cigarettes. When I was growing up, almost everyone smoked, even though anecdotally many folks believed it was harmful, despite the lack of "evidence" for that. There was in fact lots of evidence. It was just discounted.
