Freedom of speech assignment

I think there shouldn't be limits on freedom of speech, except for if said speech is harming someone in some way. And then in schools or somewhere similar, there should be some limits on what can be said and done. Like being racist or making fun of someone, that should be a bad thing. Anything that could harm others should be limited, and if possible, taken away. Every should have freedom of speech, no matter what race, age, gender, sexuality, religion, anything like that. We are all people, and we all deserve rights, especially one as important as this one.
