Thank you for sharing your concern, Ingrid. Institutions of higher education are, at their core, places for discussion and new experiences, even ones with which we don't agree. Penn State supports its faculty by allowing exploration and teaching through Academic Freedom principles, which also allows them to communicate topics that may be controversial provided it is within their field of study. I would encourage you to take a look at Penn State's information on free speech https://www.knowyourrightsandresponsibilities.psu.edu/ and more specifically on academic freedom at https://policy.psu.edu/policies/ac64

I would also encourage your daughter to discuss her concerns with her professor if she feels the political discussion is not within the scope of the coursework.
