Answer: Students may pay if the University distributes the funds in a Viewpoint Neutral Way.
Step-by-step explanation:
In the case, Board of Regents of the University of Wisconsin System v. Southworth (2000), the Court ruled that students do not need to pay fees if those fees will be used to sponsor groups that some students find objectionable if the University did so in a Viewpoint Discriminatory way.
A Viewpoint discriminatory way goes against the First Amendment clause of Viewpoint Neutrality which posits that if Government actions have the effect on stamping on a group's right to speech then they must do so for all groups and not just a few.
The University should therefore fund all the groups in a viewpoint neutral manner for the students to have to pay fees.
