I’m really not sure why this is controversial.
Do the white nationalists have a constitutional right to protest? According to the ACLU and the courts that overturned the ban, yes they do.
Do you have to like it? Of course not. But we’re Americans. You have to defend their right to protest.
A quote from Trump:
“George Washington was a slave owner… are we going to take down statues of George Washington?”
Very prophetic.
