Every society will have some non-zero number of topics associated with the “culture war” of the day.
To cater to the stigma and ignore those topics would mean subjecting discussions and experimentation to the whims of the worst political actors on any given day.
However, the callout is probably warranted. NOT discussing these to avoid culture war issues is the wrong solution, but pretending they’re not politically fraught is also incorrect. Doing so would likely lead to forgoing proper precautions for discussion of these topics, and result in worse outcomes.
It does sometimes feel like the best conversations come out of topics that no one strongly identifies with in the moment.
