Free speech is fundamental to democracy without it democracy does not exist. Similarly no one has to listen or give audience to hate groups. Unfortunately the media profits from exploiting conflict and giving audience to hate group rallies. The kkk and nazis groups are completely marginalized because their ideas are failed concepts that could not withstand the virtues of democracy and free speech that enabled modern society to evolve. Free speech has crushed intolerance and without it society would never have adopted the concept of human rights.
