Imagine a website that's based on free speech. People are having conversations. But then the racists turn up, and pretty soon all converstations end up being about THE NIGGERS and the JEWS. Most people dislike this, and so they stop using the website. But the racists love it, and they attract more racists. Soon the website is full of only racists or the usful idiots who say that freedom of speech for the racists is more important than providing a welcoming atmosphere for everyone else. This extremist version of freedom of speech is only in use in the US, and it isn't even particularly popular over there (if it were Americans would have more understanding of it). Just about everywhere else realises that limits on some types of speech are an important part of a functioning democracy.
