Why yes this is the United States of America; and yes this means you have the right to free speech. Oh by the way this freedom of speech simply means the government cannot pass laws restricting your speech. This does not mean a university that you attend, an employer or even a business that you patronize loose their rights to punish you, terminate your employment or ask you to leave.
So please exercise your rights, but quit your bitching when it has consequences. And to those complaining that protesting and identifying racial injustice is race baiting, well the real race baiting can be seen on a video out of Oklahoma and as long as there are race baiters advocating lynching then anyone who believes in equality for all should not remain silent.
