I've read through laws in america it's not illegal but in some states they have made it illegal. In the south (used to live there) there where protest all the time (ive been to atleast 6)(my bro is kinda redneck racist) but ive also been to anti hate rallys. as long as there is no violence its not illegal but once it gets outa hand thats when cops and firemen and ect. arrive. in california there are alot of gay pride protest but havnt seen any Klu klux klan or White rallies. (believe the minute one is in with 100 miles my bro lets me know) and for the record I, myself am not racist but I kinda like political history and so on so please dont take this the wrong way im just adding my input
