They can't sue the Federal Government. It is, believe it or not, against the law to do so.

#5 - those definitely are braindead mutterings! Egads.

First, you are citing an interview with an author of a meta-analysis that is presenting a defense for the study's conclusion(s). She will certainly make her case for her work. I would expect that.
Second, Meta-analysis is a tool to try and get at trends, based on qualification of, and the choices to include, other studies. It is not the answer. It is an analysis.
Third, you are ignoring the repercussions for not taking Tylenol, pretending that's a safer route. To this contributor's credit, she does not do that:

"UM epidemiologist Ann Bauer... told POLITICO... Tylenol and generic versions should remain a pain relief and fever-reduction option for them."

Importantly, you have to treat maternal fever and severe pain because they pose risks to the developing fetus, such as neural tube defects, pre-term birth, bleeding risks. So we have to present a balanced approach and alternate pain medications are not safe for use during pregnancy.

Does anyone think people are just taking acetaminophen for fun? What's the point?
