And let us not forget that glyphosate contains trace amounts of
polygrypholite binding particles which break down into trimogriphying
formucules.  While in isolation this should not be a problem, when mixed
with the sterabilating trabulaculytes it could fimulate the noonahs big

How will this affect the Monarchs?  Who knows.

You are missing something. Roundup is not purely Glyphosate.
You cannot therefore extrapolate data from pure glyphosate and apply it to
the who product. THere are other constituents too.
I would agree that you are probably right, but you have failed to establish

There are other problems.
Glyphosate _MUST_ have some effect on the soil it is sprayed on.
No question. Chemically it is N-phosphonomethylglycine.
It blocks the action of a plant enzyme called  5-enolpyruvyl-3
shikimatephosphate synthase. This is an important  enzyme in the pathway
for the synthesis of  aromatic amino acids. It doesn't occur in animals so
there isn't a problem.
It does occur in soil microorganisms so some of these must be affected.
What exactly these effects are is difficult to work out, but they must be
