Diversity of viewpoints is a complicated problem, because you don't want the diversity to be so broad that you have people who support a flat earth or people who deny the 2020 U.S. election. There is an infinite number of viewpoints, many of which should not be discussed in a university context, because they have no grounds for belief. It is a challenge. I don't think it's an impossible challenge, but how do you draw a boundary around the ideas that are worth taking seriously without excluding those who just don't agree with your viewpoint? It's a challenge that I don't think universities or funding agencies have solved, but it is one that they should take seriously.
