It is a place to discuss anything without someone removing it. Hate groups, LGBT, people for legal reasons who cannot disclose can, someone releasing information on power entities...

It is a place to find prespectives that are not allowed.

Reminds me of a star trek voyager show where bad thought has been outlawed so they have a black market for those type of thoughts. From the start there are people who want to express and someone who wants to stop them. This stops the person stopping them.
