I agree, public colleges, universities and other public-interest institutions absolutely should refuse his request to spew his racist hatred in our spaces, to us and our students.  But they won't get "walloped in court."  In fact under the law, they WILL be fined and THEY SHOULD PROUDLY & LOUDLY PAY THOSE FINES as a strong statement that, while they will abide by the Courts' legal decisions, they remain opposed to hate,  bigotry, racism and those who seek to turn American back to its white-supremacist past.  I work at a local college and I would gladly contribute to my school's legal expenses if we were asked to allow this man on our campus and we refused and were fined for doing so.

The law is a blunt instrument, it needs to protect minority speech even when that is reprehensible.  Moral conscience need not be so blunt.  We can support those who make  the hard, and in this case costly, choice to say "NO" to race-based hate.  If we change our society, we won't need to change our laws.
