You can't talk about free speech without bringing up the topic of hate speech. Hate speech is a word used to deliberately offend and threaten a certain group of people, whether based on religion, sexual orientation, race, etc. In the United States it is relatively difficult to be criminalized for hate speech, however, it will be the harmful actions taken usually related to what was previously said that will land someone in prison, not the speech itself. A famous case was Wisconsin V. Mitchell. Mitchell, a young black man, watched the film Mississippi Burn with friends. After watching the film they saw a young white boy in which Mitchell was recorded saying “Here's a white boy; go get it." The young white boy was injured and in the Mitchell case he was charged with assault and battery with increased punishment due to the beating of a child, but he was not charged with threatening and hateful speech for which you can be charged in many European countries. Flying swastika flags on your lawn is also legal, but planting them on a neighbor's lawn will lead to vandalism, not hate speech. This privilege, unfortunately, can easily be used to target and oppress other groups and it is ultimately up to society to evaluate whether or not the word has crossed a line or whether an individual realizes the potential consequences to their person.
