Discuss the rights and responsibilities associated with free speech, and describe how those rights and responsibilities have been challenged in various situations, including the appearance of individuals in public places and the occupation of public offices.
Being racist is not a crime.  Attitudes are not illegal although they can be criminally stupid.  But when someone acts out against someone else because of that attitude it could well be illegal.  Free speech like all freedoms has responsibilities and limits.  Appearing in public made up to look like a historically offensive stereotype is not illegal.  But it can be a call to violence which of course is illegal.  We can't yell "Fire" in a crowded theater remember?
And redneck fools from out of state occupying BLM offices can be considered peaceful protest except for the small fact that the idiots brought their guns.
