Where is their free speech being limited? They allow the group. Can the group not fulfill their advocacy without the use of an isu logo? Such a petty waste of time, can't wait to watch it get laughed out of court.
there is zero first amendment violation.
It not being limited. The issue is that ISU allows their trademark to be used by other advocacy groups, and has specifically singled out this group because of what it stands for. Thats most definitely a free speech issue.
