While your statement is quite vague it is no less completely inaccurate. "Supporting violence" is subjective and ambiguous. Are action movies and video games supportive of violence? How about war documentaries?

Furthermore, while "hate" speech is not the best use of our ability to communicate it does fall under the protection of free speech - at least in the United States. In some groups hate speech (however it is you describe it) is acceptable.

Just as you are free to not associate with those groups the internet should be free to express the ideas you disagree with.

You don't have the freedom to interfere or disrupt the freedoms of others.
