Safer depends how much cow manure is eaten vs how much glyphosate.

Although cow manure also has various microorganisms in it so if you got really unlucky with the wrong type of even one of those in the manure a little bit of shit could make you very sick (edit: as you point out, but my point is eating more shit exposes you to more of these on average).

Don’t eat shit or drink 1000x or 1000000x doses of something that’s safe at 1x people.

no idea where glyphosate exposure sits but even if it’s safe at normal exposure, don’t just drink it ok?

That's the point, though. From the article, the urine of 80% of the people was laced with glyphosate. It's not about a single ingestion but about it building up in the body.

Dose dependence is still a thing for long term exposure. There’s a lot of crap in urine. Knowing someone is pissing something doesn’t mean it’s toxic. We already know they’re exposed because they eat it. There is very little new information gained just by knowing people urinate it. You’d need to know how much of it they urinate compared to the amount they are exposed to and for how long to start figuring out if there is a long term build up. And even if there was no long term build up it may or may not be long term toxic. Like drinking alcohol. There is no long term build up of ethanol in the body but long term consumption of enough alcohol is still dangerous.
