People of color, women, and LGBQT in today's society can say that legally at least, they enjoy the same rights as privileged white males. The white supremacist demonstrators complain that they have no more rights than the rest of society. 

Ok even if the protesters complaint was valid, minority groups and the oppressed suffered and sacrificed greatly to gain what rights that have. You can't blame them, after their long struggles, for defending them so their children don't have to fight for them again.
