I'm not referring to telling someone to perform fellatio or calling someone names; I'm focused on the sexism here. Hate speech is, outside the law, speech that attacks a person or group on the basis of attributes such as gender, ethnic origin, religion, race, disability, or sexual orientation. There are several debates going on about how 'freedom of speech' takes hate speech into account, especially when it applies to the Internet. If it was as cut and dry as you say, and will never be a crime, I don't think there would be debates. The Internet is the wild west right now, but it's going to change. In 20 years you won't even recognize it.
