Free speech isn't about all voices being equal though, it is about the freedom to speak out against the government. It's an important distinction because the latter is needed for democracy to work where as a former doesn't work in practice because some voices should carry more weight (like subject matter experts).

Ironically the former seems more prevalent than ever with every nutjob on social media voicing their opinions, while Trump has been systematically eroding the latter with his "fake news" campaigns and reporter biases.
