A
red herring is something that misleads or distracts from a relevant or important issue.
[1] It may be either a logical
fallacy or a
literary device that leads readers or audiences towards a false conclusion. A red herring might be intentionally used, such as in mystery fiction or as part of
rhetorical strategies (e.g. in politics), or it could be inadvertently used during argumentation.
Red herring - Wikipedia
The relevant or important issue is whether life is precious, which is the underpinning argument for the pro-life argument, and all that other mumbo-jumbo on that video is a red herring because it distracts from the relevant or important issue.
